<p>In order to use urban space effectively in Transit-Oriented Development (TOD), over-track buildings (built over railways), are becoming increasingly popular in Japan. From a construction and structural design point of view, the basement structure just beneath railways generally cannot be built while railway operations continue (interruption to operations is not permitted, In general).</p><p>This paper presents the structural design of a mid-story isolated high-rise building constructed over railways in Ikebukuro, Tokyo. The paper shows, not only the philosophy of the system, but also the structural design, full-scale experiments, and evaluation of the performance in each structural element. The authors believe that such a structural design will be one of the effective solutions to the over-track building.</p>

The paper presents a comprehensive analysis of the design solution of the building of a preschool educational establishment in the city of Guastalla (Italy) with the aim of the possibility of adapting such a project to the conditions of Russian cities. A set of basic requirements for preschool buildings according to Russian building codes and rules is presented. They are grouped into four main groups: compliance with sanitary- hygienic and psychological requirements, safety, durability, cost-effectiveness, good appearance. A detailed analysis of the structural design of buildings based on a glued laminated frame with curved sections is presented from an environmental point of view. The conclusion is made about the inadmissibility of the use of glued laminated frames as a structural element of the preschool buildings. It is emphasized that the preschool building must in a special way satisfy the physiological needs of a small person. If this requirement is not met, no other advantages of the building will make it suitable for a comfortable and safe stay of children. The paper also presents a comparison of the development trends in the architecture of modern preschool buildings in the Russian and foreign practice of design and construction.

Narrative Perspective

Summary This article examines the urban themes in Leo Lipski’s micro-novel Piotruś: An ApocryphalTale from 1960. The narrative relies on both traditional realism (for the most part) and the 20thcentury subjective point-of-view technique to represent urban space, which in this case belongs to be a well-defined geographical location. The use of personalized narrative perspective turns the urban space of Tel Aviv-Jafa - heterogeneous and subject to differing assessments - into a labyrinth, closed, dense, expanding horizontally, chthonic, and alien.

Near Wall

Near-wall microenvironment of a building refers to parameters such as wind speed, temperature, relative humidity, solar radiation near the building’s façade, etc. The distribution of these parameters on the building façade shows a certain variation based on changes in height. As a technology of passive heating and ventilation, the effectiveness of this application on heat collection wall is significantly affected by the near-wall microclimate, which is manifested by the differences, and rules of the thermal process of the components present at different elevations. To explore the feasibility and specificity of this application of heat collection wall in high-rise buildings, this study uses three typical high-rise buildings from Zhengzhou, China, as research buildings. Periodic measurements of the near-wall microclimate during winter and summer were carried out, and the changing rules of vertical and horizontal microclimate were discussed in detail. Later, by combining these measured data with numerical method, thermal process and performance of heat collection wall based on increasing altitude were quantitatively analyzed through numerical calculations, and the optimum scheme for heat collection wall components was summarized to provide a theoretical basis for the structural design of heat-collecting wall in high-rise buildings.

<p>With the continuous development and progress of society, the structure of high-rise buildings has been paid more and more attention by the engineering community. However, the existing high- rise structure design methods often have a lot of redundancy and have a lot of room for optimization. Most of the existing seismic design methods of high-rise structures are based on engineering experience and manual iterative methods, so that the efficiency of design can not meet the needs of the society. if the method of design automation is adopted, the workload of designers can be greatly reduced and the efficiency of structural design can be improved. Based on the digital modeling theory, this paper proposes a MAD automatic design algorithm, in which the designer provides the initial design of the structure, and the algorithm carries out the modeling, analysis, optimization and design of each stage of the structure, and finally obtains the optimal structure. The structural design module of this algorithm starts from the component level, when the component constraint design meets the limit requirements of the specification, it enters and completes the component constraint design and the global constraint design of the structure in turn. In this paper, taking a ten-story braced steel frame high-rise structure as an example, the optimal design is carried out, and its seismic performance is analyzed. the results show that the MAD automatic design algorithm can distribute the materials to each part reasonably, which can significantly improve the seismic performance of the structure and realize the effective seismic design.</p>

The paper explores the compact city concept based on the «spatial» urban development principles and describes the prerequisites and possible methods to move from «horizontal» planning to «vertical» urban environments. It highlights the close connection between urban space, high-rise city landscape and conveyance options and sets out the ideas for upgrading the existing architectural and urban planning principles. It also conceptualizes the use of airships to create additional spatial connections between urban structure elements and high-rise buildings. Functional changes are considered in creating both urban environment and internal space of tall buildings, and the environmental aspects of the new spatial model are brought to light. The paper delineates the prospects for making a truly «spatial» multidimensional city space.

The design of skyscrapers involves lot of aspects such as the building must withstand heavy dead loads, should have safety measures against fire, floors must be easily accessible, and should have resistant against wind and seismic loads that can be detrimental to the safety of the skyscraper. Pile foundations are usually adopted for high rise buildings and when it is combined with raft slab they ensure that the problems of differential settlement are taken care of. In this paper the scenario of designing a skyscraper in seismic zone that is prone to earthquakes and the ground condition is such that it is located in vicinity of sea. Andaman and Nicobar isle is one similar place it falls under Zone V as per Indian Standards, hence prone to seismic activity and since it is surrounded by Bay of Bengal and Andaman sea, when seismic activity occurs there is a high chance of soil liquefaction to occur hence proper structural designs should be embraced.

Failure of some elements in the structure can play triggering role for beginning of collapse progression. The critical element is the structural element that when it fails, leads to progressive collapse. To find the critical element of the structure, sensitivity analysis should be done. But there are not specific structural criteria for using in sensitivity analysis. In this paper following GSA, UFC 4-023-03 and ASCE guidelines, sensitivity analysis has been modified and applied to find the critical element of a major number of reinforced concrete structures. 1080 3D nonlinear pushdown analyses were done and the results showed that the place of the critical elements differs in different stories and different plan shapes of high rise structures. In the structures with high aspect ratio in height, the critical element of the whole structure is located in the story of 2/3 height of the structure. When the aspect ratio of the structure in plan increases, sensitivity of the columns in the long dimension of the structure become closer to each other.
