Abstract: |
A suitable method based on the reduced basis conception,is proposed for efficiently analyzing and computing the structural static extreme response.In this method,the finite element model is established firstly,and then the reduced basis method and genetic algorithm are used together to construct a reduced optimization model,which could rapidly obtain the structural static extreme response at single-observation point.To further improve engineering application of this method,the largest extreme displacement response under multi-observation-point situation is taken into consideration in development of the optimization model and procedure.The examples in this paper demonstrate the high accuracy and efficiency of this method. |
