摘要：竖向分布钢筋不连接装配整体式剪力墙(SGBL装配整体式剪力墙)特点包括：剪力墙中竖向分布钢筋在楼层处断开连接，两端边缘构件采用现浇做法同时加大主筋配筋，从而极大的提高施工效率。由于SGBL装配整体式剪力墙的配筋形式较传统装配整体式剪力墙配筋形式存在较大差异，因此应提出针对于SGBL装配整体式剪力墙的极限位移计算方法。通过分析竖向钢筋配筋形式变化对SGBL装配整体式剪力墙等效塑性铰长度的影响，提出了考虑剪切、弯曲变形影响的SGBL装配整体式剪力墙极限位移计算方法，并通过SGBL装配整体式剪力墙抗震试验的结果验证了计算方法的可靠性，为SGBL装配整体式剪力墙基于位移的变形能力设计方法提供参考。

Displacement-based deformation capacity design method of monolithic assembled concrete shear wall with non-connected vertical distribution reinforcement
Abstract: The characteristics of the monolithic assembled concrete shear wall structure with non-connected vertical distribution reinforcement(SGBL monolithic assembly shear wall) are that the vertical distribution reinforcements are unconnected at the floor and the boundary elements at both ends are cast-in-situ and the main reinforcement is increased at the same time, which greatly improves the construction efficiency. As the reinforcement forms of SGBL monolithic assembly shear wall structure are quite different from those of traditional monolithic assembly shear walls, a calculation method for the ultimate displacement of SGBL monolithic assembly shear wall structure was proposed. By analyzing the influence of the change of vertical reinforcement form on the equivalent plastic hinge length of SGBL monolithic assembly shear wall structure, a calculation method for the ultimate displacement of SGBL monolithic assembly shear wall structure was proposed considering the influence of shear and bending deformation, and the reliability of the calculation method was verified by the seismic test results of SGBL monolithic assembly shear wall structure. It provides a reference for the displacement-based deformation capability design method of SGBL monolithic assembly shear wall structure.
Keywords: SGBL monolithic assembled shear wall; vertical distribution reinforcement; ultimate displacement; equivalent plastic hinge; bending deformation; shear deformation
