AN INPROVED ELASTO-PLASTIC SPECTRUM FOR THE SEISMIC BEHAVIOR ASSESSMENT AND DESIGN OF SHEAR WALL STRUCTURES
A simplified ductility based elasto-plastic response spectrum method to solve the seismic demand in plastic stage was introduced in this paper. Recently, the performance based seismic design method was given importance and developed rapidly. Seismic demand solving and structure assessment method was published,the IDA and N2 methods was applied more often. A simplified ductility based elasto-plastic response spectrum method which combine N2 method and the native seismic code considering the influence of site category was introduced. Ductility coefficient was used as a key parameter to solve the nonlinear seismic demand in this method which realized multi level seismic demand solving. Shear wall failure discipline was sum up and the structure performance level is divided combining with FEMA273 and the native seismic design code. A shear wall design example was enumerated to explain the process of the ductility based elasto-plastic response spectrum method. The conclusion indicated that the ductility based elasto-plastic response spectrum method could be applied to the seismic design of the performance predetermined structure, this method was simple and reliable in the seismic demand solving, and could be amended and put into practice.
