中文摘要：
对6个门式刚架边柱节点试件进行了反复荷载试验。试验中试件出现3种破坏变形模式。以子构件为基础分析了试件的变形能力、延性及耗能能力。试验结果表明,节点域屈曲过程中形成的拉力场保证了节点域局部屈曲破坏的抗震能力。如侧重于门式刚架抵抗罕遇地震作用,则剪切屈曲模式优于构件的局部屈曲破坏模式,节点域剪切屈曲过程中的耗能能力可以加以利用。文中所采用的承载力计算方法可以有效地预测构件和节点局部屈曲的承载力和对应的破坏模式。
英文摘要：
Six specimens were tested under cyclic loading to study the hysteretic behavior of the connection of beam to side column in steel gabled frames. Three different failure modes were observed from the test. The deformation capacity, ductility and energy dissipation capacity were analyzed. The test results show that the tension field formed in the process of local buckling in panel zone ensures the earthquake resistance of panel zone after local buckling. The shear buckling is a favorable failure mode compared with the local buckling of slender members under rare earthquake. The energy dissipation in the process of shear buckling of the panel zone can be used. The calculation method adopted is able to predict the local buckling capacity of members and panel zone, and the corresponding failure modes.
