Abstract

This paper investigates reliability-based optimization of structural anti-disaster. At first, the random pushover analysis method was developed, and the pushover-bound analysis was proposed, which is used to identify structural dominant failure modes by generation of failure path. At second, a process of seismic reliability-based optimization of structural system base on control was proposed. By nesting the optimization of the weakest failure modes in control model, the control of structural system reliability was realized. Actual calculation example showed that structural reliability can be improved effectively by this method. The research in this paper has certain significance of basic research of structural anti-disaster reliability.
