摘要
通过有限元分析得到顶底角钢半刚性连接的受力情况以及上角钢塑性铰发展状况,根据这些特点给出相应的力学模型,并提出顶底角钢半刚性连接极限弯矩的计算公式。将计算公式与有限元分析结果进行比较,二者相吻合,表明提出的顶底角钢半刚性连接极限弯矩计算公式具有一定的参考价值。
The stress of top- and seat-angle semi-rigid connections and development of plastic hinge were obtained through finite element analysis. According to these characteristics, a new mechanical model of calculating the ultimate moment Of the connections was put forward. The result of the finite element snalysis is consistent with that of the mechanics model through comparing, which indicates that the mechanical model was correct.
