A Review Paper on Progressive Collapse Assessment of Asymmetric High Rise Building and its Modelling using ETABS Software

In the article there will be a consideration of collapse process progressive simulation of a high-rise building by removing the first-floor columns. The object of the study will be a 27-storeyed high-rise building. The high-rise building structural concept will consist on a monolithic reinforced concrete frame. The mounting base structural concept has been modeled as absolutely rigid. Static and dynamic calculations have been performed in the «Ing +» software complex, while the wind load pulsating component was taking into account using the finite-element method for the spatial slab-and-rod model. The dynamic calculation analysis has shown the obtained oscillation forms corresponding to the design requirements. The stress-strain behavior has been studied for the floor slabs as reinforce constructive of a typical floor. Structural concepts for the building frame of a high-rise building have been developed to reduce the progressive collapse risk. In the physically non-linear calculations, with the removal of the first-floor corner and central columns, four options for the sandwich floor slabs reinforcing were taking into account. The rational reinforcement option has been selected, in which the building is resistant to progressive collapse. The building frame structural concept with the floor slabs heavy-duty reinforcement of the first five floors has been suggested. An outrigger floor with encircling reinforced concrete trusses along the outer contour was included to reinforce the load-carrying framework. Recommendations on the choice of rational structural concepts, reducing a high-rise building progressive collapse risk have been given.

Due to the safety awareness arisen from natural and human-caused disasters, robustness design of building is increasingly important to ensure the stability of the building and to prevent progressive collapse. For this reason, the robustness design of innovative construction technologies such as modular construction may be essential due to its relative novel structural form and numerous joints among modules. Particularly in Singapore, Prefabricated Prefinished Volumetric Construction (PPVC) has been highly promoted in residential and commercial buildings, hostels and hospitals to boost the construction productivity and quality as well as to reduce the reliance on foreign workforce. PPVC offers high quality and efficiency because most of the finishes and mechanical and electrical services are manufactured and installed together with the modules in factory, before sending for on-site assembly. To maximize the productivity of PPVC, modular design standardization and repetition can be improved by going for high-rise. Nonetheless, there are limited studies on the robustness of PPVC high-rise building and its behavior under progressive collapse remains uncertain. Therefore, this paper investigates the robustness of steel PPVC high-rise building under column removal scenarios by conducting non-linear numerical analysis. The effects of joint design and diaphragm action between modules are studied to ensure continuity of horizontal and vertical tying. This paper provides insight on the behaviour and alternative path for load transfer under column removal scenario for future design guideline of robustness PPVC building.

This article deals with the problem of security and resistance of the high-rise unique buildings to progressing collapse. The analysis of the causes of accidents and collapses of buildings and structures is carried out. The features of calculations and verification of structures for progressive destruction are explored. The analysis of researches and updating of norms on emergency prevention is carried out. The ways of solving the problems of buildings structural schemes resistance and structures to progressive collapse are shown. Particular attention is paid to the use of outrigger communication floors to improve the level of building survivability. Examples are reviewed from the high-rise buildings construction practice on the territory of the Russian Federation. Recommendations are given for the development of further research and practical application of measures to increase resistance to the progressive collapse of high-rise buildings.
