Abstract:

Traditional reliability analysis considers only “safety, failure” teo level working mode, i.e. from safety to failure, structures are transilient, but actual engineering commonly works with intermediate state. It is a kind of “safety, intermediate state, failure” three level working mode. A reliability analysis method of earthquake resistance of multi storey steel structure with intermediate state is put forward by statistical parameter for seismic load. It is useful to reliability analysis of actual engineering for reference to petroleum industry.

Key words: reliability analysis, intermediate state, multi storey steel structure, earthquake resistance, structural bottom shear
