Abstract

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.

Highlights

The volume of high-rise unique buildings construction in Russia abroad increases significantly
A major problem in the high-rise unique construction development is the lack of comprehensive all-Russian legal requirements governing high-rise construction
This fact definitely restrains the construction of high-rise buildings throughout Russia

Summary

Introduction

The volume of high-rise unique buildings construction in Russia abroad increases significantly. This is due to a land shortage with a good urban perspective, price increase, as well as the intention to concentrate administrative buildings in certain financial centers. A major problem in the high-rise unique construction development is the lack of comprehensive all-Russian legal requirements governing high-rise construction. This fact definitely restrains the construction of high-rise buildings throughout Russia. A significant contribution to the development of research on the prevention of progressive destruction was made by V.O. Almazov, who gave recommendations on the calculation, proposed options for buildings strengthening, investigated the dynamics of progressive collapse, suggested a technique for determining the dynamic coefficient, which depends on the frame height.
