摘要
在建筑工程中,以往对钢板剪力墙结构简化模型的验证多基于拟静力或单调加载进行,而很少关注其动力时程分析。为了研究简化模型在动力分析方面的适用性,论文取1个单跨4层的非加劲钢板剪力墙结构为基本模型,通过有限元软件ABAQUS采用精细模型对其进行了时程分析,并将其与多种简化等代模型分析结果进行比较。分析表明,混合杆系模型不仅能够准确地预测钢板剪力墙体系振动过程中的位移和加速度响应,而且能够估计钢板墙边缘框架内力,是1种有效的简化模型,具有用于实际设计分析的潜力。
The verification of simplified models of steel plate shear walls is mostly based on quasi-static or monotonic loading analysis,while the dynamic time history analysis is rarely concerned about.In order to research dynamic applicability of simplified models,this paper presents time-history analysis on a one-span four-story experimental unstiffened steel plate shear wall specimen by using the refined model and multiple simplified models.The result of finite element analysis indicates that combined strip model which can not only forecast dynamic response of the SPSW,but also estimate internal force of peripheral frame is an effective simplified model,and has the potential to use to actual design.
