Roofs covering buildings in the city of Bam, Iran prior to the earthquake of 26 December 2003 can be categorized into three main groups: traditional masonry dome or vault, steel I-beam jack-arch system, and concrete beam-hollow block system. The collapse of nonengineered masonry roofs and floor slabs during the earthquake was the single largest contributor to the large number of fatalities. This paper discusses the seismic performance of each type of roofing and their strengths and weaknesses. The poor seismic performance of traditional domes and vault roofs and unanchored jack-arch slabs are noted and the seismic merits of the anchored jack-arch slabs and concrete beam-hollow block slabs are discussed.

Initial Cracks

The experimental work on two full-scale precast concrete beam-column corner joints with corbels was carried out and their seismic performance was examined. The first specimen was constructed without steel fiber, while second specimen was constructed by mixed up steel fiber with concrete and placed it at the corbels area. The specimen were tested under reversible lateral cyclic loading up to ±1.5% drift. The experimental results showed that for the first specimen, the cracks start to occur at +0.5% drifts with spalling of concrete and major cracks were observed at corbel while for the second specimen, the initial cracks were observed at +0.75% with no damage at corbel. In this study, it can be concluded that precast beam-column joint without steel fiber has better ductility and stiffness than precast beam-column joint with steel fiber. However, precast beam-column joint with steel fiber has better energy dissipation and fewer cracks at corbel as compared to precast beam-column joint without steel fiber.

… surely there would be men enough, willing and glad to contribute to the regeneration of the poor outcasts of the city. It is no longer an experiment since the Children's Aid has removed of this class, in thirteen years, eleven thousand two hundred and seventy two! Who would not rejoice to aid in such an enterprise…? Money only is wanting. Shall that be an insurmountable obstacle in the way of accomplishing such an unspeakable blessing? New York Children's Aid Society, 1866 Annual Report

PurposeThe lives of the poor in the urban spaces of India are filled with hardships. They live amidst poverty and struggle to survive within other problems such as insecure jobs, lack of proper housing, unsanitary conditions and low levels of health immunity. This vulnerable section of the population has been rendered furthermore vulnerable by the outbreak of the COVID-19 pandemic in ways that were never imagined before. Taking this into consideration, the purpose of this article is to examine the vulnerability of the poor in the urban settings of India with special reference to Mumbai in the context of the COVID-19 pandemic.Design/methodology/approachThe methodology adopted in the study is based on the analysis of secondary data and content analysis of the existing literature. In addition to this, the study also makes use of certain narratives of the urban poor in Mumbai that have been captured by various articles, reports and blogs.FindingsThe findings of the study reveal how the urban poor of India, with special reference to Mumbai, the financial capital of India, has emerged as the worst sufferers of the socioeconomic crisis caused by the social distancing and lockdown measures imposed for combating the pandemic.Originality/valueThe study tries to explore the reality of the urban poor's right to the city in the wake of the pandemic.

In the past decade, significant social movements emerged in South Africa, in response to specific urban challenges of injustice or exclusion. This article will interrogate the meaning of such urban social movements for theological education and the church. Departing from a firm conviction that such movements are irruptions of the poor, in the way described by Gustavo Gutierrez and others, and that movements of liberation residing with, or in a commitment to, the poor, should be the locus of our theological reflection, this article suggests that there is much to be gained from the praxis of urban social movements, in disrupting, informing and shaping the praxis of both theological education and the church. I will give special consideration to Ndifuna Ukwazi and the Reclaim the City campaign in Cape Town, the Social Justice Coalition in Cape Town, and Abahlali baseMjondolo based in Durban, considering these as some of the most important and exciting examples of liberatory praxes in South Africa today. I argue that theological education and educators, and a church committed to the Jesus who came ‘to liberate the oppressed’, ignore these irruptions of the Spirit at our own peril.

This work explores the experience of team participation the University of Cruz Alta Cruz Alta Rio Grande do Sul, Rondon Project. With goal to integrate the student to reality Brazil, and develop political, economic, and health care activities education for the poor, in January 2012, teachers and students visited the city of Aguiarnópolis, state of Tocantins in Brazil. The project is the intellectual effort of research and understanding of the process history, involving the saga of Brazilian Cândido Mariano Rondon and his legacy to the formation of anthropologists. This study proposes a reflection on Rondon Project while the university democratization of space public, considering it essential to approach institution with society. The Rondon Project is an extension activity that aims to consolidate the sense of social responsibility in university, knowledge on different Brazilian realities and production local collective projects.  It is intended, finally, contribute through this study to highlight the importance of alliance between scientific knowledge and empirical in everyone's life citizens, and the contribution of the Rondon Project to provide this exchange of knowledge between students and underserved communities.

Tramp panhandler (Gelandangan Pengemis, called: Gepeng) is a social phenomenon that is a problem for every region in Indonesia. Gepeng is a promising job for some communities. Gepeng in Serang itself varies, from which can still suffice the need to be said to be sufficient and not including the poor households (RTM), to the poor who really belong to poor households (RTM). This article aims to analyze the background of the emergence of sprawl in Serang city. This paper uses the research method of the library study, discussing the sprawl in the city of Serang to provide the correct problem solving the mitigation in the city of Serang in an effort to realize social welfare. From the results of the study obtained data that the cause factor of the person chose to be a sprawl; Physical disabilities, age, education, economics, environment and religion.

The 6th of April 2009, a quite strong earthquake of magnitude ML =5.8 (Mw=6.3), struck in the city of L'Aquila. The seismic event caused serious injure to several masonry buildings, compromising a large part of the valuable historical and architectural heritage. The present work deals with seismic performance evaluation of an existing mixed masonry-reinforced concrete building in downtown L'Aquila city. A comprehensive discussion on the current limit capacity of the building based on the visual inspections of the occurred seismic damage, the experimental data from a wide campaign of on-site tests on the material properties, the results of numerical simulations from different naturally discrete models of the mixed masonry-reinforced concrete structure are presented. The seismic performance is evaluated through well-recognized N2 nonlinear static procedure. The Frame by Macro-Elements method is used to define an equivalent 3D frame representation of the structure. The obtained numerical results are directly compared with the surveyed damages.
