针对预制装配式剪力墙结构,提出了内置空心管的混凝土填充墙与实体剪力墙墙肢一同浇筑生产、安装施工的预制一体化剪力墙结构。通过5个外形尺寸、墙肢和连梁配筋相同的混凝土双肢剪力墙的拟静力试验,探究了无填充、砌块砌体填充和一体化整体填充的剪力墙抗震性能,总结了这三类墙体的破坏形态、受力特点、承载与变形能力、刚度、延性和耗能能力的特点。试验结果表明:预制一体化剪力墙在水平往复荷载作用下发生弯剪破坏,相比于无填充墙试件和砌体填充试件,其抗侧刚度和受剪承载力有明显提高,同时具有良好的抗震性能。最后,基于Open SEES平台对拟静力试验结果进行了有限元验证,得到了吻合程度较好的滞回曲线、骨架曲线及墙肢纵筋应变;根据试验结果与有限元分析,提出了预制一体化混凝土剪力墙结构合理的填充墙构造方案。
According to the prefabricated shear wall structure, a prefabricated integrated shear wall structure with the built-in hollow concrete filled wall and the solid shear wall is put forward. Through the quasi-static tests of five reinforced concrete double-limb shear walls with the same overall dimensions and with the same reinforcement, the seismic performance of the shear wall without filling, masonry block filling and integral whole filling is explored. The three types of wall damage morphology, stress characteristics, bearing and deformation capacity, stiffness, ductility and energy consumption characteristics. The test results show that the precast integrated shear wall is bent and sheared under the horizontal reciprocating load. Compared with the unfilled and the masonry-filled specimens, the lateral stiffness and shear capacity of the prefabricated integrated shear wall are obviously improved. Has a good seismic performance. Finally, based on the Open SEES platform, the results of the quasi-static test were verified by finite element method, and the hysteresis curve, the skeleton curve and the longitudinal reinforcement strain of the wall and arm were obtained. According to the experimental results and the finite element analysis, Construction of a reasonable structure of infilled walls with concrete shear walls.
