摘要:
提出装配式交叉密肋钢板剪力墙结构,利用有限元分析方法建立纵横密肋钢板剪力墙试验有限元模型,验证建模方法的有效性及可靠性; 建立交叉密肋钢板剪力墙有限元模型,选取内嵌钢板高厚比、密肋钢板网格尺寸2个参数进行变参分析,对比各系列试件的滞回曲线、黏滞阻尼系数、骨架曲线及刚度退化情况,分析内嵌钢板墙几何参数对交叉密肋钢板剪力墙滞回性能的影响,并给出两参数的合理取值范围。结果表明:内嵌钢板高厚比λ≥500时,试件耗能能力、侧向承载能力及延性等性能随内嵌钢板高厚比的减小而显著提升,当λ<500时,上述性能提升幅度不明显,内嵌钢板高厚比λ建议取值500～600; 交叉密肋网格尺寸对试件滞回性能影响显著,试件各项性能随交叉密肋网格尺寸的减小而提升,且提升幅度与网格尺寸减小幅度呈正相关,交叉密肋网格肋板条数建议取值小于等于5×5。
Abstract:
The assembled cross-ribbed steel plate shear wall structure was proposed, the finite element analysis method was used to establish the finite element model of shear wall test of longitudinal and transverse multi-ribbed steel plate, and the validity and reliability of the modeling method was verified. The finite element model of cross-ribbed steel plate shear wall was established, the embedded steel plate height thickness ratio, multi-ribbed steel plate grid size were selected for variable parameters analysis, and the hysteretic curve, viscous damping coefficient, skeleton curve and stiffness degradation of each series of specimens were compared. The influence of geometric parameters of embedded steel plate wall on the hysteretic performance of cross-ribbed steel plate shear wall was analyzed, and the reasonable range of two parameters was given. The results show that when the height thickness ratio of the embedded steel plate λ≥ 500, the energy dissipation capacity, lateral bearing capacity and ductility of the test specimen increase significantly with the decrease of the height thickness ratio of the embedded steel plate. When λ<500, the above performance improvement is not obvious, and the recommended value of the embedded steel plate height thickness ratio λ is 500-600. The grid size of cross ribs has a significant effect on the hysteretic performance of specimens. The performance of the specimen increases with the decrease of the grid size of cross rib, and the increasing range is positively related to the decreasing range of the grid size. It is suggested that the number of cross-ribbed grid ribs should be less than or equal to 5×5.
