【摘要】 叠合连梁为高层装配整体式剪力墙结构中的重要构件，其抗震效果直接决定剪力墙结构的抗震能力。为此，对高层装配整体式剪力墙结构叠合连梁的抗震性能进行评估。制备不同跨高比、不同锚固方式的高层装配整体式剪力墙结构叠合连梁试件，模拟了地震作用下各试件的抗震性能。试验结果显示：地震荷载较小时，各试件的破坏情况均不严重，仅叠合连梁边缘位置出现少量裂缝；随着地震荷载的增大，各试件的裂缝逐渐增多，损伤面积不断扩大，其中跨高比较高的试件损伤面积较小，裂缝分布面积较小。当连梁转角较大时，跨高比较高的试件梁端弯矩变化较小，其高层装配整体式剪力墙结构叠合连梁具有较为良好的抗震性能。更多还原

【Abstract】 Composite connecting beam is an important component in high-rise assembled integrated shear wall structure, and its seismic effect directly determines the seismic capacity of shear wall structure. Therefore, the seismic performance of the composite connecting beam in high-rise assembled integrated shear wall structure is evaluated. In the prefabrication plant, the composite connecting beam specimens of the high-rise assembled integrated shear wall structure with different span to height ratios and different anchoring methods are prepared, and the seismic performance of each specimen under earthquake action is simulated. The test results show that under the condition of small earthquake load, the damage of the three specimens is not serious, and only a few cracks appear at the edge of the composite connecting beam. As the seismic load increases, the number of cracks in each specimen increases and the damage area expands. Among them, specimens with high span to height ratios have the least damage area and the smallest crack distribution area.When the turning angle of the connecting beam is large, the bending moment change at the beam end of the specimen with high span height ratio is relatively small, and the composite connecting beam of the high-rise assembled integral shear wall structure with high span height ratio has good seismic performance.更多还原
