隅撑支撑钢框架结构抗震性能分析
|
摘要
采用pushover方法对单角隅撑支撑钢框架在三种罕遇地震烈度下的抗震性能进行分析,得出该结构在不同罕遇地震作用下的破坏模式及抗震性能点,并对其抗震性能进行评定;该结构在地震作用下塑性铰依次出现在隅撑、斜支撑及框架梁上,从而可以消耗大量的地震能量,同时避免了框架柱遭受破坏,符合"强柱弱梁"的设计要求。
The pushover method was applied to analyze the anti-earthquake performances of the knee bracing steel frame 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,and the structure has been assessed the anti-earthquake performances under the different earthquakes.Under the earthquake plasticity hinges appear from knee brace to ordinary brace the last is on the beam,it can consume earthquake energy to protect the column being destroyed at the same time.The result indicates the knee bracing steel frame adjust to the requirement of strong column and weak beam.
