带缝剪力墙及外砌保温空心砖抗震稳定性试验研究
|
摘要
通过对外砌保温空心砖带缝剪力墙体进行水平低周反复加载试验,研究了外砌页岩保温砖墙的破坏形态、变形能力和抗震稳定性能以及混凝土剪力墙的变形和抗震性能.研究结果表明,外砌页岩保温空心砖墙体具有较好的抗震稳定性;设置竖缝可以改变构件的破坏形态,合理设置竖缝,在承载力下降较小的情况下,可以较大程度改善剪力墙的变形性能,同时使结构具有较好的抗震性能.
Through carrying out the low cyclic load tests on the shear wall with seams and insulating hollow bricks cladded outside,this paper studies the failure modes and deformability and aseismic stability of the wall cladded with insulating shale bricks,and the deformability and aseismic stability of concrete shear wall.The results show that the wall cladded with insulating shale hollow bricks demonstrates better aseismic stability,and the vertical slits can change the failure modes,and if the vertical slits are set properly,the deformability of the shear wall will be improved greatly as the bearing capacity decreases slightly.
