摘　　要：轻钢门式刚架结构具有自重轻,抗震性能好等优点。然而,现行门式刚架节点的构造和受力性能并不理想,为了改善门式刚架节点受力性能,文中在研究传统节点的基础上提出改良型节点形式,用ANSYS软件进行循环荷载作用的滞回性能检验、比较,对关键部位进行应力分析。结果表明,改良后门式刚架节点承载力有了大幅的提高,抗震性能也有了明显的改善,为工程应用和理论研究提供了宝贵的资料。The portal rigid frame with its light and good seismic performance has been widely applied to building engineering.But,the corresponding design specification for the frame is not perfected.Therefore modified connections are proposed.The digital repeated loading tests on the modified connection modes were stimulated by using the ANSYS to obtain their hysteretic behavior and stress of key parts.The results show that the modified connections are better than the common ones in load capacity and seismic performance.
