Topological analysis of contemporary morphologies under conflict: The urban transformation of Dobrinja in Sarajevo and the Central District of Beirut

Regarding topological interpretation of space, this research aims to identify urban morphologies, whose topology becomes increasingly determining under high uncertainty. This topological approach has been applied in an evolutionary analysis of urban spaces under siege, fear and conflict, which conducted to the construction of a specific method. This method analyses the transformation of urban areas in five consecutive phases: urban form [1], increase of uncertainty [2], application of the apparatus [3], change in urban form [4], information flows [5]. These five phases were applied to different empirical studies, analysed through specific morphological and topological models. In the light of this method, two selected urban morphologies Dobrinja –a suburb in Sarajevo– and the Beirut Central District have been examined. The urban morphology of both areas was dramatically transformed after both civil conflicts –the Bosnian War and the Lebanese Civil War–. Dobrinja suffered severe modifications, first provoked by the violence of the siege during the Bosnian War [1992-1995], and then by the Inter-Entity Boundary Line as a result of the Dayton Peace Agreement [December 1995], which divided the neighbourhood and caused serious alterations in its ethno-demographic and spatial structure. The Beirut Central District was first destroyed by the violence experienced in the Lebanese Civil War [1975-1990] and then by the process of subsequent reconstruction [since 1992], which led to a simplification of its structure. The two morphological and topological analyses enable us to determine the initial causes and their spatial consequences in both urban areas, regarding their conflict and post-conflict stage.

The Nine Forms of the French Riviera: Classifying Urban Fabrics from the Pedestrian Perspective.

The Nine Forms of the French Riviera: Classifying Urban Fabrics from the Pedestrian Perspective. Giovanni Fusco, Alessandro Araldi ¹Université Côte-Azur, CNRS, ESPACE - Bd. Eduard Herriot 98. 06200 Nice E-mail: [email protected], [email protected] Keywords: French Riviera, Urban Fabrics, Urban Form Recognition, Geoprocessing Conference topics and scale: Tools of analysis in urban morphology Recent metropolitan growth produces new kinds of urban fabric, revealing different logics in the organization of urban space, but coexisting with more traditional urban fabrics in central cities and older suburbs. Having an overall view of the spatial patterns of urban fabrics in a vast metropolitan area is paramount for understanding the emerging spatial organization of the contemporary metropolis. The French Riviera is a polycentric metropolitan area of more than 1200 km2 structured around the old coastal cities of Nice, Cannes, Antibes and Monaco. XIX century and early XX century urban growth is now complemented by modern developments and more recent suburban areas. A large-scale analysis of urban fabrics can only be carried out through a new geoprocessing protocol, combining indicators of spatial relations within urban fabrics, geo-statistical analysis and Bayesian data-mining. Applied to the French Riviera, nine families of urban fabrics are identified and correlated to the historical periods of their production. Central cities are thus characterized by the combination of different families of pre-modern, dense, continuous built-up fabrics, as well as by modern discontinuous forms. More interestingly, fringe-belts in Nice and Cannes, as well as the techno-park of Sophia-Antipolis, combine a spinal cord of connective artificial fabrics having sparse specialized buildings, with the already mentioned discontinuous fabrics of modern urbanism. Further forms are identified in the suburban and “rurban” spaces around central cities. The proposed geoprocessing procedure is not intended to supersede traditional expert-base analysis of urban fabric. Rather, it should be considered as a complementary tool for large urban space analysis and as an input for studying urban form relation to socioeconomic phenomena.

Impact of Bridges on Spatial Transformation of Urban Pattern: The case of Golden Horn, Istanbul

Transportation projects especially subways, bridges and new transportation modes gained importance in İstanbul in the last decades. The Golden Horn Metro Bridge, which connects two parts of the European side of İstanbul and has a station on the bridge, has caused criticisms not just because of having these unique characteristics but also because of the effects of the bridge on the silhouette of Historical Peninsula. The main aim of this paper is to analyze the impact of bridges on urban pattern and to explore the different influences of metro and vehicular bridges. Within this scope, three bridges located over the Golden Horn, which created connections between historical site of İstanbul and the newly developed CBD, are chosen as study case. Areas within 1km zones around the bridges are analysed separately, and the urban pattern (street pattern, block size, building utilization) is investigated comparatively through GIS. The layers of the past geographies (Historical GIS) and the Space Syntax (angular segment based integration and choice) analyses are conducted for demonstrating the changes in the spatial organization. The findings indicate that the study area has transformed into more divided streets and urban blocks and the number of buildings increased through time. Moreover, it is observed that the metro-rail bridge system has less impact on urban pattern when compared with the vehicular bridges. This study contributes to urban planning/design not only by analysing comparatively the transformation of the urban pattern during the pre- and post-construction processes of the bridges but also by evaluating the impact of the bridges through a quantitative and innovative method.

Urban efflorescences of the global and the local: An analysis of the territory of Gipuzkoa (Spain)

Plaza Oñati, 2. 20018 Donostia-San Sebastián. E-mail: [email protected]. Tel. Num: 943015907 Keywords (3-5): Urban centrality, global exposure, territory of Gipuzkoa, spatial patterns Conference topics and scale: Tools of analysis in urban morphology, territorial scale The present study deals with the changes generated in the last decades by the increasing globalization in order to discern its influence on the urban structure of Gipuzkoa. The incidence of globalization in the processes of urban transformation is perceived, on the one hand, in the tendency towards the concentration of economic activities and, on the other, in the stimulus received by the local level and by the specialization, as generators of urban concentration. The urban forms that have arisen in this territory as a result of the global exposure present a varied typology as a consequence of the multiple scopes and scales in which they have been developed. Far from pretending to cover them all, the present study analyses a sample of urban processes and effects that have taken place in the territory of Gipuzkoa in the last decades, such as: science and technology parks, specialized networks around local products, processes of museification of industrial and rural environments, or expansion of the tourism services network. The study of these processes will attend both to their particular urban manifestation and to their territorial incidence, through the use of diverse sources and techniques to obtain a map in which they can be studied together. The resulting map of the sum of the different indicators will reveal characteristic spatial patterns of this centrality associated to the effect exercised by the sphere of the global over the local.

Study for a new definition of the southern side of Prato della Valle in Padua, Italy

The southern limit of thePrato della Valle space in the southern part of Padua's historical centre, inItaly, was continuously delimited by the boundary wall of the Santa Maria dellaMisericordia convent until the early twentieth century. Its presence was one ofthe elements that more than a century ago inspired the enlightened proposal byDomenico Cerato, a design professor at the University of Padua who had beeninspired by Andrea Memmo, the Superintendent of the Serenissima Republic ofVenice. The straight and continuous limit was replaced by the discontinuousarchitecture of the Foro Boario entrance, built in 1913 according to a designby Alessandro Peretti; this weakened the overall solution based on anelliptical shape, as did the communicative power of the nearby basilica ofSanta Giustina. The examination carried out dwells on these limits, simulatingthe virtual introduction of architecture with a continuous front to thesouthern edge of the Prato della Valle. One example of this type ofarchitecture is the Nelson-Atkins Museum of Art built in Kansas City between1930 and 1933, based on a design by the brothers Thomas and William Wight, andexpanded in 1999 based on a design by Steven Hall. The study generallyconfirmed that the compactness of the building's front newly provides strengthto Cerato's design, which gave a sense of unity to the general emptiness thanksto the certainty of its borders, and gives again the Basilica of Santa Giustinaits monumental size. This paper investigates the composition ofheterogeneous fragments, excerpts from the inventory of collective memory, andthe resulting unpredictable architecture in an urban context.

Energy Efficiency in the Urban Scale: Case Study – Prague, Czech Republic

Cities are a complex mass of morphological properties of many city fragments, which play a major role in energy consumption. Urban form, urban patterns, or city fragments can also be seen as defined by algorithms or form generators. Cities are designed taking into account infrastructure, city standards and land use regulations. Energy efficiency of the urban form may be understood as the balance between gains and losses of energy, which may depend on a set of parameters mostly defined by the geometrical shape of the buildings and the distance between them. The study starts from the development and analysis of 60 hypothetical models in order to evaluate their energy efficiency potential. The Galapagos Evolutionary Solver is used as a tool in order to find the set of parameters, which brings to the morphological properties the optimal combination of density and surface-to-volume ratio. At the final stage morphological properties of 64 Prague’s patterns were selected. Computer simulation and analysis is performed using the models extracted from the virtual Google Earth model of Prague. During the process of evaluation of the samples, the relationship between the urban form and such parameters as plot coverage, surface-to-volume ratio and the incident solar radiation was established and potentially higher energy efficient structures were indicated. As the result of analysis the interrelation between urban form and energy efficiency was established, which allowed to identify the urban patterns with the higher potential of energy efficiency.

A study on the history of urban morphology in China based on discourse analysis

A study on the history of urban morphology in China based on discourse analysis Limeng Zhang¹, Andong Lu¹ ¹School of Architecture and Urban Planning, Nanjing University. Nanjing University Hankou Road 22#, Gulou District, Nanjing, China E-mail: [email protected], [email protected] Key words: urban morphology, terminology, discourse analysis Conference topics and scale: Literature review (Supported by the Natural Science Foundation of China, Grant No.: 51478215) Urban morphology is a method widely used in China in the field of urban design and urban conservation. Since its first introduction to the Chinese context about 20 years ago, the key ideas and concepts of urban morphology underwent a significant phenomenon of ‘lost in translation’. Different origins of morphological thoughts, different versions of translation, as well as different disciplinary context, have all together led to a chaotic discourse. This paper reviews the key Chinese articles in the field of urban morphology since 1982 and draws out a group of persistent keywords, such as evolution, axis, urban fringe belt, plan unit and plot, that characterize the morphological approach to urban issues. By reviewing the transformation of the definition of these keywords, this paper aims to generate an evolutionary map of landmark ideas and concepts, based on which, four stages in the development of urban morphology in China can be identified: emergence, growth, maturity, practice. The mapping methodology could be extrapolated to other words, and the obtained evolutionary map could be a basic tool for further study. References Conzen M. R.

Recovering the Habitat concept within Urban Morphology

The purpose of this paper is to provide an opportunity to explore the Habitat debate within ISUF. We quest that within this concept, as placed by Moudon (1997) in her inaugural paper to Urban Morphology, there is an intrinsic call towards an equilibrium between the various dimensions of urban form and a trans-disciplinary approach to the study of urban form, which deserves further investigation.According to Whitehand (2012) specific constrains affected the full concretization of such trans-disciplinary efforts, namely the further specialization of the disciplinary areas. Moreover, as argued by Marat-Mendes (2016), the focus placed by urban morphology on the physical dimensions of urban form has been significantly higher than on the social or human dimensions of the urban form, thus affecting in turn the above-identified equilibrium. In order to contribute to such debate, this paper presents the results of an ongoing investigation (Marat-Mendes, Cabrita, 2015), which seeks to recuperate the concept of Habitat within urban morphology. To do that, it first identifies the concept of Habitat as it was first defined in a number of seminal works to urban morphology (Demangeon, 1926). Secondly, it exposes how did such concept evolved throughout specific historical, disciplinary and methodological contexts (Deyong, 2011). And thirdly, it reveals the impact that such evolution had on the various problematics and scales of approach by those to which the Habitat issue was central for the study of urban from, including some contemporary contributions from various interdisciplinary areas, which seem to be recuperating that concept, although not explicitly.

Practices and forms of open space at territorial scale: A comparison between two cities crossed by minerals rivers.

A scientific reading of the transformations of Matera starting from the urban re-activation in a social and spatial perspective in its neighbourhoods. The redevelopment of urban voids starts by the metaphor of the ecological network in an urban scale to update the connection system of open spaces in the light of new practices and flows for an innovative idea of urban resilience. The key role is re-see the neighbourhood: (i) on a local scale, focusing on the practices and customs, in the centre like in the industrial areas, starting processes of recovery and reuse but also of innovation (that result from the opportunity to be the European Capital of Culture 2019); (ii) on a urban scale with the transition space and threshold, identifying those natural and mineral signs representing a transition of porosity. The value of the "suburbs" enters as re-starting for rebirth of the city projects counting on the creativity of practices into the open spaces. The reformist project of Matera as original "laboratory" of architectural and urban experiments changes. Neighbourhoods were born from the same idea of “vicinato” (neighbour) but adapted to a new social identity, able to work on embryos of community, in the same way in Valencia in which natural elements (Turia) lead to rediscover the sense of belonging and making community. In both cases, urban policies are oriented towards innovative and spontaneous processes able to change the urban approach to a multi-purpose city although representative of culture and identity.

Typology based on three density variables central to Spacematrix using cluster analysis

Since the publication of the book ‘Spacematrix. Space, density and urban form’ (Berghauser Pont and Haupt, 2010), the Spacematrix method has been linked back to its theoretical foundations by Steadman (2013), is further developed using the measure of accessible density to arrive at a density measure that more closely relates to the environment as experienced by people moving through the city (Berghauser Pont and Marcus, 2014) which then is used to arrive at a multi-scalar density typology (Berghauser Pont et al. 2017). This paper will take yet another step in the development of the Spacematrix method by including the measure of network density in the classification which until now was not used to its full potential. Important for successful classification is the ability to ascertain the fundamental characteristics on which the classification is to be based where the work of Berghauser Pont and Haupt (2010) will be followed addressing three key variables: Floor Space Index (FSI), Ground Space Index (GSI) and Network density (N) where especially the last was not fully included in the earlier work. Besides a typology based on these three variables, this paper will also result in a robust statistical method that can later be used on larger samples for city-scale comparisons. Two statistical methods are tested: hierarchical clustering and centroid-based clustering and besides a general discussion about their strong and weak points, the paper shows that the hierarchical method is more convincing in distinguishing differences in both building type and street pattern that is especially captured with Network density (N). As this method is not useful for large datasets we propose a combination of the two clustering methods as the way forward.
