Abstract

The thought of research on vibration control of construction is given out and corresponding mathematical model is established. Based on the model characteristics of optimization of seismic reduction structure and mathematical principle of main optimization algorithm, pattern search algorithm is chosen for damper parameter optimization analysis. Through secondary development of ANSYS, damper parameter optimization program of seismic reduction structure is established. Through searching for extreme value of one multi-peak functions pattern search algorithm is established to be effective. The results show the optimization algorithm of this paper and corresponding program can realize the parameter optimization analysis effectively and accurately. At last process of optimization analysis under different seismic waves proved the stability of the algorithm.
