摘要:
本文提出一种新型装配式剪力墙体系,即墙板水平分布筋、竖向分布筋顶部与现浇带可靠连接,竖向分布筋底部不贯通,仅坐浆连接。为了研究这种新型墙体的抗震性能,本文设计了两组不同剪跨比下的共7个剪力墙试件,并对其进行拟静力试验,参照现浇剪力墙,分析不同剪跨比、边缘构件尺寸、边缘构件纵筋率下的新型装配式剪力墙在低周往复荷载下的破坏模式、承载力等抗震性能。试验结果表明:新型墙体首先在连接处开裂,最终墙板与边缘构件和坐浆层分离;与现浇剪力墙相比,新型墙体的承载力较低,但变形和耗能相差不大;加强边缘构件可以弥补对墙板竖向钢筋不连续的削弱,新型墙体在高层建筑中应用的可行性较大。本文为新型装配式剪力墙结构的发展提供了试验基础。
Abstract:
A new type of precast concrete shear wall system is proposed in this paper, which is the horizontal distribution of the wall panels, the top of the vertical distribution ribs and the cast-in-place belt are reliably connected. It does not penetrate to the bottom of the distribution ribs, and is only connected by building mortar. In order to study the seismic performance of this new type of wall, a total of seven shear wall specimens with different shear-to-span ratios were designed and pseudo-static test was carried out. Referring to cast-in-situ shear walls, the failure modes and bearing capacity of new precast concrete shear walls under low cyclic reciprocating loads are analyzed under different shear span ratios, size of edge members and longitudinal reinforcement ratio of edge members. The test results show that the new wall first cracks at the joint, and eventually the wall panels are separated from the edge members and the slurry setting layer, compared with cast-in-situ shear wall, the bearing capacity of the new wall is lower, but the deformation and energy dissipation are similar, strengthened edge members can compensate for the discontinuous weakening of the vertical reinforcement of the wallboard, this new type of wall in high-rise buildings is feasible. This paper provides an experimental basis for the development of new precast concrete shear wall structures.
