摘要
对1个钢筋混凝土剪力墙试件、1个后浇带连接的预制混凝土剪力墙试件和1个榫卯接缝连接的装配整体式剪力墙试件开展拟静力试验研究,研究了不同构造接缝的连接性能及其对墙体受力性能的影响。结果表明,榫卯接缝的连接性能较好,可保证墙体的整体性,对受弯承载力无不利影响;峰值荷载后,沿榫卯接缝的横向凹槽底部截面形成竖向裂缝,有助于提高墙体的变形能力,减小根部混凝土压溃区域;后浇带接缝剪力墙开裂较早且发展较快,对承载力影响较大,榫卯接缝的连接性能优于后浇带连接接缝。
The pseudo-static tests of three shear wall specimens including one cast-in concrete shear wall,one precast concrete shear wall with post-pouring strip joint and one assembled monolithic shear wall with mortise-tenon joint were carried out to study the connection behavior of different joints and the influence of these joints on the mechanical properties of the walls.The results show that the connection performance of mortise-tenon joint is very well,which can ensure the integrity of the wall and has no effect on the bending bearing capacity.After peaking load,vertical cracks are formed along the bottom section of transverse groove in the mortise and tenon joint,which are helpful to improve the deformability of shear wall and reduce the crushing area of root concrete.The cracking of post-pouring strip joint appears earlier and develops faster,which has great influence on bearing capacity.The connection behavior of mortise-tenon joint is better than that of post-pouring strip joint.
