摘　　要：为了研究混凝土翼板外伸锚固的梁柱端板连接半刚性组合边节点力学性能,设计了3个足尺试件,其中两个混凝土翼板外伸150mm,厚度分别为140mm和200mm;另外一个为混凝土翼板未外伸的对比试件。采用柱顶水平位移控制低周循环加载试验,分析了锚固对该半刚性组合边节点力学性能的影响。结果表明,混凝土翼板外伸锚固(尤其是外伸锚固部分加厚)能够提高该半刚性组合边节点的稳定性及其抗震能力。因此,在实际施工中,应该尽可能锚固。3 full scale specimens were designed in order to study mechanical properties of the semi rigid composite exterior joint with the beam to column end-plate connection that concrete slab overhangs. In 2 of 3 specimens, the overhang length of concrete slab is 150 mm and the thickness of which is 140 mm and 200 mm respectively. The other specimen has no overhang for comparison. The low cycle loading experiment controlled by the horizontal displacement of the column top is conducted and the effect of the anchorage on mechanical properties of the semi-rigid composite exterior joint is analyzed in this paper. The results show that the anchorage of concrete slab with overhang may increase the stability and seismic performance of the semi-rigid composite exterior joint. It is more obvious when the thickness of the concrete slab with overhang is increased, specially. Therefore, the anchorage should be used as far as possible in the actual construction.
