通过1个钢筋混凝土剪力墙和4个装配式空心模板剪力墙的拟静力试验,研究了剪力墙的抗震性能及竖向接缝构造对墙体受力性能的影响。试验结果表明,装配式空心模板剪力墙沿内部接缝出现宏观竖向裂缝,经历了整截面墙受力到墙柱组合体受力的过程,可防止脆性破坏,较钢筋混凝土剪力墙变形能力显著增强、受剪承载力降低;峰值荷载前沿竖向接缝两侧的相对变形将墙体分割为分缝剪力墙,提高了延性和耗能能力,降低了受剪承载力;竖向接缝处采用木板条补替部分混凝土可改善墙体的受力性能;按照强弯弱剪设计的墙体,水平接缝对墙体受力性能的影响可以忽略;装配式空心模板剪力墙的竖向接缝受力性能良好,可用于实际工程。 Through a quasi-static test of a reinforced concrete shear wall and four assembled hollow formwork shear walls, the seismic performance of the shear wall and the influence of vertical joint structure on the performance of the wall are studied. The experimental results show that the macroscopic vertical cracks appear along the internal joints of the assembled hollow-form shear walls, which are under the stress of the whole cross-section wall to the columns and pillars, which can prevent the brittle failure, as compared with the deformation of the reinforced concrete shear walls And the shear capacity decreases significantly. The relative deformation of the vertical joints on the front of the peak load divides the wall into divided shear walls, which improves the ductility and energy dissipation and reduces the shear capacity. The vertical Replacing part of the concrete with wood slats in the seams can improve the mechanical performance of the wall. According to the wall with strong weak scissors, the influence of the horizontal joints on the mechanical properties of the wall can be neglected. The assembled hollow-form shear wall The vertical joint force performance is good, can be used for practical engineering.
