摘要:

为研究带预制混凝土(PC)填充墙剪力墙的抗震性能,完成了8个缩尺比为1/2的剪力墙试件拟静力往复加载试验,研究了试件的破坏形态、滞回曲线、骨架曲线、刚度、耗能和延性等性能。结果表明:带窗洞填充墙试件易发生弯剪破坏,剪力墙破坏变得更为严重; 相比无填充墙试件,带填充墙试件的极限承载力和刚度明显提高,滞回曲线普遍呈弓形; 考虑门洞填充墙试件的耗能及延性与纯剪力墙相差不大; 考虑窗洞填充墙试件的延性与纯剪力墙相差不大,但耗能能力有较为明显的提高; 当同时考虑门洞和窗洞填充墙时,试件的破坏形态与单窗试件相同,耗能有所降低,延性与纯剪力墙试件相同; 窗洞口给试件提供了足够的变形能力,窗台则提供了较大的刚度和承载力; 填充墙结构相比于现浇结构整体性较差,无法充分发挥材料的耗能能力,当墙体中填充部分太多时,无填充墙试件耗能能力反而大于同时带有门洞和窗洞填充墙的试件。

Abstract:

In order to study the seismic performance of shear wall with prefabricated concrete(PC)infilled wall, quasi-static cyclic loading tests on eight 1/2 scaled shear wall specimens were completed, and the failure mode, hysteresis curve, skeleton curve, stiffness, energy dissipation and ductility of specimens were investigated. The results shows that the wall specimens filled with window openings are prone to bending and shear failure, and shear wall failure becomes more severe. Compared to the specimen without infilled wall, the ultimate bearing capacity and stiffness of the infilled wall specimen are significantly improved, and the hysteresis curve is generally in a bowed shape. The energy consumption and ductility of the specimen with door are not much different from that of the pure shear wall. The ductility of the specimen with window is not significantly different from that of pure shear wall, but the energy consumption of the specimen has been significantly improved. When considering both the door and window, the failure mode of specimen is the same as that of the single window specimen, the energy consumption is reduced, and the ductility is the same as that of pure shear wall specimen. The window provides sufficient deformation capacity, while the window sill provides greater stiffness and bearing capacity. Compared to the cast-in-place structure, the infilled wall structures is less integrated, ant it is unable to fully utilize the energy dissipation capacity of material. When there is too much filling in the wall, the energy dissipation capacity of the unfilled wall specimen is actually greater than that of the specimen with both door and window openings filled in the wall.
