摘　　要：为解决装配式建筑混凝土剪力墙结构在受到地震荷载作用时的强度和刚度问题,提出一种新型钢板-螺栓连接的装配式剪力墙结构,深入对比研究现浇剪力墙与采用钢板-螺栓连接的装配式剪力墙结构。研究结果表明,这两种结构体系的骨架曲线均展现出明显的S形变化特征,钢板-螺栓连接的装配式剪力墙结构在抗震承载力和初始刚度方面显著优于现浇剪力墙结构。此外,增加轴压比有助于进一步提升装配式剪力墙结构的抗震性能。数值模拟与物理模拟的结果高度一致,误差率较低,从而验证了物理模拟试验在可靠度和精度方面的优势。To solve the strength and stiffness problems of prefabricated building concrete shear wall structures under seismic loads,in this paper,a kind of assembled shear wall structure with steel plate-bolt connection is proposed.Based on the comparative study of cast-in-place shear wall and fabricated shear wall structure with steel plate-bolt connection,the results show that the skeleton curves of the two systems exhibit obvious s-shape variation characteristics.It is worth noting that the fabricated shear wall structure with steel-plate-bolt connections is significantly superior to the cast-in-situ shear wall structure in terms of seismic capacity and initial stiffness.In addition,the increase of axial compression ratio can further improve the seismic performance of the fabricated shear wall structure.The results of numerical simulation are in good agreement with those of physical simulation,and the error rate is low.
