Survivability Analysis of Reinforced Concrete Frameworks of Multi-storey Buildings Made of Frame-panel Elements Using Combination of Prefabricated and Monolithic Concrete in Case of Accidental Impacts Caused by Loss of Stability of One of the Columns In connection with the new proposals to improve the structural systems of large-panel housing construction (LPHC) on the basis of the use of panel-frame designs, as well as in connection with the release of new normative documents, which contain requirements for the accounting of accidental impacts and for the protection of buildings and structures against progressive collapse, there is a request to develop methods and algorithms to calculate such systems for survivability and against progressive collapse. The loss of stability of one of the bearing elements caused by accumulation of corrosion damages in this element or corrosion of separate connections and fixings of this element should be considered as one of accidental impacts on constructive system. The article presents an algorithm and numerical analysis of stability of the frame fragment of a multi-storey building made of panel-frame elements at removal one or more fixings, that lead to loss of stability of one of the columns of the building. The proposed computational technique allows to check the resistance of the structural system to progressive collapse under such influence and to make proposals to protect the frame of the building against progressive collapse.

Keywords: combination of prefabricated and monolithic concrete, survivability, progressive collapse, loss of stability

Regional housing construction in the Volga Federal District on the example of the capital region has far-reaching plans in accordance with the «Draft Strategy of the Nizhny Novgorod Region until 2035». The accumulated potential of the historical experience of one of the key regions of the country in conjunction with the architectural and urban development opportunities provides the acceleration of sustainable development for years ahead. Social and human origins in conjunction with cultural and economic opportunities and resources are the initial criteria when preparing and implementing housing programs in Nizhny Novgorod. In order to achieve high rates of housing construction for the next six years, the idea of the need to repeat the experience of «people’s construction of the 1950s»is argued. On the example of the Nizhny Novgorod region initiating the legal consolidation of the high status of the agglomeration, additional opportunities of super-dense high-rise development under the harsh conditions of urbanization and high-dense low-rise residential development are opened for the approval of de-urbanization positive, the development of large areas of the valleys for settling in the new territories.

Keywords: housing program, urbanization, high-dense development, architectural-construction peculiarities, region, agglomeration, sustainable development, de-urbanization.

Light-Urban Simulation in Formation of Comfortable Urban Environment The article is devoted to the simulation of artificial light environment of urban development. The research in the search for methods and means of humanization of the human environment and light-color structuring of the architectural space of cities has been carried out. Light-urban modeling, as a section of the urban development project of the city, affects the professional solution of the problems of interaction of artificial light with structural-forming elements. The methodology has been developed and recommendations for the design of light-urban complexes at three stages in the process of formation of a comfortable urban environment are made. At present, the system solution of composite problems of artificial lighting is becoming a matter of professionals and specialized firms. In the near future innovative technologies and materials of a new generation for providing the operation of architectural lighting systems will play an increasingly important role and have a lasting importance in the implementation of ambitious programs of light urbanization of the country.

Keywords: artificial light environment, light-urbanistics, urban environment, comfort, living environment humanization, structuring of architectural space of city, light-urban complex.
