Calculation of the load-bearing structures of buildings based on the critical group of limit states

Abstract

This paper examines improvements to the method for calculating building structures under a specific limit state not covered by the regulatory document currently in force in the Republic of Uzbekistan. In the design of buildings and structures, the calculation of limit state criteria boundaries is considered for the effects of short-term accidental loads (explosions, vehicle impacts, falling loads, earthquakes, avalanches, mudslides, etc.), the probability of which is low. The failure of load-bearing vertical and horizontal members distributed across the plan and height of a building may result in varying risks of failure for adjacent members. This paper examines the incorporation, within the design of buildings and structures, of a differentiated assessment of the contribution of their load-bearing members using the limit state method.
