| Abstract: | In the elastio-plastic seismic analysis of a multi-degree-of-freedom system structure,seismic input motion parameters and structure dynamic parameters are considered.The method of estimating input energy for multi-degree-of-freedom system structures is presented.With the analysis of the example,it is shown that the procedure to get the input energy demand of multi-degree-of-freedom system structures using the method based on equivalent single-degree of freedom systems is a simple,effective and exact method. |
