| Abstract: | In the field of seismic research on long-span structures,multi-support response spectrum method has got much attention and rapid development due to its attractive characteristics such as terse form,explicit physical meaning as well as convenient application.Moreover,this method has also been used in the seismic analysis of some critical engineering projects.In this paper,the research developments in multi-support response spectrum method at home and abroad are firstly presented in detail,and then the application status of the method are provided,including seismic response analysis and seismic reliability analysis of long-span structures based on the method.Finally,some problems needing further investigation are proposed. |
