| Abstract: | According to the reqiurements of the code for seismis design of buildings,the elasto-plastic time-history method is adopted to analyse the structure.Considering the factors influencing the reliability of the time-history method,the rational selection method of seismic wave is studied.In order to improve the defects of current selection of seisimic wave,it is suggested to use the elastic total input energy as the complemental method under consideration of the influence of motion duration.A nonlinear soft IDA... |
