Abstract

A novel method is presented to determine the external dynamic forces applied on structures from measured structural responses in this paper. The method utilizes a new SVM-CPSO model that hybridized the chaos particle swarm optimization (CPSO) technique and support vector machines (SVM) to tackle the problem of force identification. Both numerical simulations and experimental study are performed to demonstrate the effectiveness, robustness and applicability of the proposed method. It is potential that the proposed method is practical to the real-life application.
