摘要:为研究带预制混凝土(PC)填充墙的装配式联肢剪力墙抗侧刚度与水平承载力计算方法,完成了1个无填充墙和2个带PC填充墙试件的低周往复荷载试验,考察了PC填充墙对装配式联肢剪力墙抗侧刚度和水平承载力的影响,在试验基础上建立了结构简化分析模型,提出了联肢剪力墙抗侧刚度和水平承载力计算方法。结果表明:带PC填充墙的装配式联肢剪力墙试件整体性较好,PC填充墙的存在可提高试件的抗侧刚度和水平承载力;PC填充墙与联肢剪力墙的连接形式对试件的抗侧刚度和水平承载力有较大影响;基于连续化计算方法提出的带PC填充墙的装配式联肢剪力墙抗侧刚度和水平承载力计算方法,计算结果与试验值吻合良好。

Abstract: To study the calculation method of lateral stiffness and horizontal bearing capacity of prefabricated coupled shear wall with precast concrete(PC) infill wall, the low-cyclic loads tests of one specimen without infill wall and two specimens with PC infill wall were completed, and the effects of PC infill wall on lateral stiffness and horizontal bearing capacity of prefabricated coupled shear wall were investigated.Based on the tests, a simplified structural analysis model was investigated.The calculation method of lateral stiffness and horizontal bearing capacity of coupled shear wall was proposed. The results show that the integrity of the prefabricated coupled shear wall with PC infill wall is good, the existence of PC infill wall can improve the lateral stiffness and horizontal bearing capacity of the specimen. The connection form of PC infill wall and coupled shear wall has a great influence on the lateral stiffness and horizontal bearing capacity of the specimen; Based on the continuous calculation method, the anti-side stiffness and horizontal bearing capacity of the prefabricated coupled shear wall with PC infill wall is proposed by the continuous calculation method, and the calculation results are good with the experimental value.
Keywords: prefabricated coupled shear wall; precast concrete infill wall; flexible connection; rigid connection; lateral stiffness; horizontal bearing capacity
