Abstract:

The features of seismic analysis of long-span structures and the three methods which are commonly used in analyzing the seismic response of long-span structures under multi-support excitations are briefly stated, and then the research developments of multi-support response spectrum method at home and abroad are presented in detail. Finally, some problems needing further investigations are proposed.
