Hybrid simplex artificial bee colony algorithm and its application in material dynamic parameter back analysis of concrete dams

Abstract

The hybrid simplex artificial bee colony algorithm which combines artificial bee colony algorithm with the Nelder-Mead simplex search method for improving the search efficiency in computation is proposed.The algorithm is applied to identify the material dynamic parameters of concrete dams by establishing an optimization inverse calculation model based on incomplete modal test data.Application example shows that the proposed algorithm possesses the advantages of both artificial bee colony algorithm and Nelder-Mead simplex search method,which have the features of quick convergence and high accuracy of identification.
