摘要:
基于等代框架法的有限元模型,应用带刚域的弹塑性杆单元来模拟短肢剪力墙的连梁,并考虑剪切变形影响,对肢强系数、整体性系数、翼缘宽度和连梁配筋率等参数不同的短肢剪力墙进行了弹塑性分析,研究了这些参数对短肢剪力墙弹塑性性能的影响.结果表明,在墙肢截面和配筋率一定时,随着肢强系数的增加、整体性系数的减小和连梁配筋率的降低,短肢剪力墙的承载能力降低,延性增加; 而随着墙肢翼缘宽度的增加,短肢墙的承载力和延性都增加.因此在设计中,通过合理选择这些参数,可以使短肢剪力墙具有较高的承载力和良好的延性.
Abstract:
Based on equivalent frame finite element model, using frame elements with stiffness areas to simulate the coupling beams of short pier shear walls, and taking the influence of shear deformation into account, the elastoplastic analyses of short pier shear walls with different pier strength coefficients, integrate coefficients, flange widths of piers, and the reinforcement ratios in coupling beams were implemented. The influences of these parameters were studied. The results indicate that with the increase of pier strength coefficient as well as the decrease of integrate coefficient and the rebar ratio in coupling beams, the load capability of short pier shear wall decreases, however, its ductility increases on condition that the cross sections and their rebar ratios keep constant. In addition, with the increase of flange width of piers, both the load capability and ductility of the wall increase. Therefore, by reasonably choosing these parameters in design, the wall can be made with better performances in load capacity and ductility.
