Damage Identification of Two-Stage Beam Structure Based on Improved Particle Swarm Optimization Algorithm

Abstract

In the process of using the engineering structure in complex environment, due to the influence of various factors, it will inevitably produce different degrees of damage, cracking or aging, which will bury hidden dangers and endanger the safety of the structure itself, the safety of human life and the loss of property. Therefore, damage identification of structures has important practical significance to reduce losses. In this paper, an improved particle swarm optimization algorithm is proposed for damage identification of two-stage beam structure. Then use isopso to determine the best point to use multiple standards.
