Abstract:In General Rule for Performancebased Seismic Design of Buildings,there are many new aseismic conceptions and calculating methods,such as performancebased design,basic design ground motion acceleration,plastic seismic response of structures,structural influence coefficient,structural elasticplastic sidesway,vertical seismic response of high frequency structures,category of seismic of buildings etc.It will promote the seismic design of the buildings,and it may be used as the model code to adjust the Code for Seismic Design of Buildings in China.
Keywords:performancebased seismic design；buildings category；structural influence coefficient；plastic seismic sidesway
