摘要:
为了验证新型全装配式钢筋混凝土剪力墙(IPSW)结构中竖向缝连接的可行性并研究其抗震性能,制作了2个竖向缝连接试件,并对其进行低周反复荷载试验.试验结果表明, 翼缘墙板与腹板墙板之间的连接件(内嵌边框、高强螺栓和连接钢框)能够有效地传递二者之间的相互作用力,保证二者协同工作.然后,分别基于最大拉应力理论、平截面假定和力的平衡条件、抗剪抵抗机构和力的平衡条件,建立了开裂荷载、屈服荷载、极限抗剪承载力的计算模型,并推导了理论公式.结果表明,开裂荷载、屈服荷载以及极限抗剪承载力的试验值与理论值吻合较好.由此可见,IPSW结构的竖向缝连接方案可行,特征荷载的计算模型及计算公式合理.
Abstract:
In order to verify the feasibility of vertical joints in an innovative precast shear wall(IPSW)system and investigate their seismic behaviors, two specimens were manufactured and low-cyclic reversed loading tests were carried out. The test results show that the connectors between the flange wall panel and the web wall panel, including the embedded limbic steel frame, the high-strength bolt and the connecting steel frame, can effectively transfer the interactional forces between the two wall panels and make them work cooperatively. Based on the maximum tensile stress theory, the plane cross-section assumption and the equilibrium condition of forces, and the shear resistant mechanism and the equilibrium condition of forces, the calculation models and theoretical formulas for the cracking load, the yield load, and the ultimate shear capacity were deduced, respectively. The results show that the test values of the cracking load, the yield load, and the ultimate shear capacity agree well with the corresponding theoretical values. Therefore, the novel scheme of vertical joints in IPSW system is feasible, and the calculation models and theoretical formulas for characteristic loads are reasonable.
