钢板剪力墙结构的简化模型研究
|
摘要
统一等代模型(USM)和混合杆系模型(CSM)是从纯拉杆模型(SM)基础上发展起来的两种钢板剪力墙结构简化模型。本文在已有试验研究基础上,通过有限元软件ABAQUS对采用精细模型和简化模型的钢板剪力墙结构进行了单调荷载弹塑性分析和动力时程分析,基于理论推导对USM模型进行了修正,并给出了CSM模型的理论荷载-位移曲线,同时讨论了CSM模型应用于时程分析的适用性。结果表明:相比于SM模型,USM模型估计的极限承载力具有更高的精度,但初始刚度提升不明显;虽然CSM模型估计的初始刚度精度很高,但是当墙板高厚比较大时,其承载力高于精细模型,而CSM模型应用于动力时程分析时,对于墙板高厚比大于250的钢板剪力墙结构模拟等效结果较为准确。该研究为钢板剪力墙结构的简化模型应用提供一定参考。
The Unified Strip Model( USM) and the Combined Strip Model( CSM) are two simplified models of non-stiffened steel plate shear wall structures,and both models develop from Strip Model( SM). Based on the existing experimental researches,the software ABAQUS is used to perform the monotonic loading elastic-plastic analysis and the dynamic time-history analysis of the steel plate shear wall with fine model or simplified model. Based on the theoretical deduction,the USM model is modified and the theoretical load-displacement curve of CSM model is given. Besides,the applicability of CSM model to time-history analysis is also discussed. The results show that,compared with SM model,the USM model estimates the ultimate bearing capacity with higher accuracy,but the initial stiffness is not improved significantly. Although the simulation of the initial stiffness is very precise by using CSM,the bearing capacity of CSM is much higher than that of the fine model when height-thickness ratio of the wall plate is large. However,when the CSM model is applied to the dynamic time-history analysis,the simulation equivalent result of the steel plate shear wall structure with height-thickness ratio greater than 250 is much accurate. This study provides some reference for the application of the simplified model of steel plate shear wall structure.
