中文摘要：
利用静力弹塑性的分析方法，对考虑组合效应的梁腹板开圆孔型钢框架进行分析．为了便于对比，分别根据有无混凝土楼板和有无开孔削弱，选取了四个类型的框架，采用SAP2000进行建模计算；利用已有的研究成果，定义了节点的塑性铰模型．通过两种侧向荷载分布模式的计算得到了不同结构的Pushover曲线、结构的位移和塑性铰的分布情况．研究表明：考虑混凝土楼板的组合效应后，结构的刚度和承载力增加；腹板开圆孔削弱则对结构整体性能的影响非常小．
英文摘要：
The behavior of steel frame with opening in beam web considering the effect of composite ac- tion is been analyzed using the Pushover analysis method in this paper. In order to contrast, we select four types of steel frame, respectively, according to whether there are concrete slabs and the opening in beam web. These frames are modeled and calculated using the SAP2000 finite dement software. The plastic hinge model define of the joints is from the existing research results. Pushover curves, dis- placements and the distribution of plastic hinges of the different structures under two lateral load distri- bution pattern are calculated. The results show that, the composite action of concrete slab might in- crease the strength and bearing capacity of the structure and the weakening on the performance of the whole structure due to the oDening in beam weh is very small.
