摘要:
与传统钢板剪力墙结构不同,箱板式组合加劲钢板墙没有周边框架梁和框架柱,并且由墙板与加劲肋共同承受水平与竖向荷载.为解决一般加劲钢板墙在地震作用下面外变形大、刚度退化快、滞回捏缩严重等不足,提出一种组合加劲钢板墙形式.在对3个组合加劲钢板墙试件进行拟静力试验研究的基础上,对其进行有限元分析.探讨了钢板墙高厚比λ、肋板刚度比ηL和ηT及螺栓排布形式等三种参数对组合加劲钢板墙抗震承载力的影响.研究结果表明,肋板刚度比η对极限承载力的影响较小,钢板墙高厚比λ与螺栓排布形式对组合加劲钢板墙的抗侧刚度和极限承载力影响显著.基于试验和参数分析结果,提出组合加劲钢板墙受力模型; 并考虑高厚比、加劲板与钢板的滑移两个关键参数的影响,建立了组合加劲钢板墙抗剪承载力计算公式.分析结果表明,所提计算公式能准确的反映该种钢板墙截面的受剪屈服程度,具有良好的计算精度和适用性.
Abstract:
Different from the traditional steel plate shear wall structure, the box-plate composite stiffened steel plate wall has no surrounding frame beam and column. And the wall panel and stiffeners jointly bear the horizontal and vertical loads. In order to solve the disadvantages of general stiffened steel plate wall under earthquake action, such as large external deformation, fast stiffness degradation and severe hysteresis pinching, a composite stiffened steel plate wall(CSSPW)is proposed. The finite element analysis of three CSSPW specimens are carried out on the basis of quasi-static tests. The three parameters of the depth-thickness ratio λ of CSSPW, stiffness ratio ηL and ηT and arrangement of bolts on the seismic capacity of CSSPW were explored. Results show that the stiffener-plate stiffness ratioη of the ribbed plates has less influence on the ultimate bearing capacity. The depth-thickness ratioλ and the arrangement of bolts of CSSPW has a significant influence on the lateral stiffness and ultimate bearing capacity. Based on the results of test and parameter analysis, the force models of CSSPW are put forward. In addition, considering the influence of two key parameters, the thickness ratio and the slip between stiffener plate and steel plate, the formula for calculating the shear capacity of CSSPW is established.Results show that the proposed formula can accurately reflect the shear yield degree of the wall section of this kind of steel plate, and has good accuracy and applicability.
