| 摘 要： | 用数值分析方法对梁腹板开设矩形洞口的削弱型节点和没有削弱的梁柱节点进行了分析。分析表明,梁腹板削弱型节点有足够的塑性变形能力,可以达到减小节点表面梁翼缘处的应力,迫使塑性铰外移的目的。

| Abstract: | It is analysed the reduced beam section connections with rectangular openings on beam web and unreduced beam section by use of the finite element method. Based on design procedure introduced, the reduced beam section with rectangular openings on beam web shows better performance than unreduced beam section connections. This connection can reach the purpose of forcing the plastic hinge away from the face of the column and reduce the strain of beam flange near the connection. |
