交错桁架结构体系的破坏模式及抗震性能分析

Analysis on failure mode and anti earthquake performances of cross truss structure system

采用push-over方法对钢结构交错桁架体系在三种罕遇地震烈度下的抗震性能进行了分析,得出了交错桁架体系在罕遇地震作用下的破坏模式及塑性铰的发展过程,并对交错桁架结构体系的设计提出了几点建议。

The push - over method was applied to analyze the anti - earthquake performances of the steel structure cross truss system under three kind rare earthquake intensities. The failure mode and plasticity hinge developing processing under the rare earthquake function of the cross truss system were obtained. The paper had several proposals on the design of the cross truss system.
