State of Research in Response Spectrum for Multi-supported Structures

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.

Key words:long-span structures; multi-support excitation; response spectrum method; seismic response
