Abstract

This paper presents damage identification method for 10 and 25-bar plane truss structures based on inverse problem. Models for both structures are built in MATLAB software using FEM. A new optimization technique investigated recently, namely a chimp optimization algorithm (ChOA), is used. The objective function is based on measured and calculated frequencies and mode shapes, and used to analyse the convergence study of the fitness and damaged elements. Modal assurance criteria (MAC) are used to represent the mode shape in the objective function. The ChOA provided good results for both structures after a few iterations.
