摘　　要：结合实际情况,对3个钢梁-混凝土刚接节点试件进行了低周反复荷载试验,3个节点的破坏形态、滞回曲线特性、刚度变化等一系列受力性能表明,试件的延性及耗能能力均满足抗震设计要求,螺栓规格的提高能显著提高节点的承载力及抗震性能,连接板厚度的增加也能提高节点的承载力及抗震性能,但效果不是很明显。On the basis of the former researches practice,low reversed cyclic load experiment on three rigid joints of steel beam and concrete wall were taken.The damage shape,hysteretic curve and stiffness change of the three rigid joints were analyzed.It is revealed that the durability and energy dissipation capacity of the three rigid joints can meet the seismic design requirements.The carrying capacity and seismic performance of the joint increase significantly with the bolt diameter increasing.The increasing of connection plate thickness could improve their performance as well,but the effect was not clear.
