【摘要】 针对传统结构可靠性分析仅考虑"安全-失效"二级工作模式,而实际工程中往往存在中介状态的问题,考虑了结构的"安全-中介-失效"三级工作模式,利用地震作用下结构底部剪力、层剪力等的概率分布特点,建立了具有中介状态的多层钢框架结构抗震可靠性分析方法。为石油行业多层钢结构的抗震性分析提供了依据。更多还原

【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.更多还原
