摘要
无屈曲波纹钢板剪力墙是一种兼具承载和耗能功能的新型钢板剪力墙,在工程中应用前景良好。而在工程设计中,由于波纹钢板几何形状较为复杂和现有结构设计软件的局限性,有限元建模较为复杂和繁琐。为此,依据无屈曲波纹钢板墙的受力特性提出了多种不同的基于连接单元的简化分析模型,通过对比分析选取了水平轴向连接单元模型作为波纹钢板剪力墙的简化分析模型,给出了模型参数确定的原则;借助通用有限元分析软件Abaqus评估其模拟精度,并通过参数化分析考察了该简化模型的普适性。最后,对钢框架-无屈曲波纹钢板剪力墙结构中简化模型的适用性进行了分析,给出了边缘构件内力的修正方法,供设计人员参考。
The non-buckling corrugated steel shear wall is a new type of steel plate shear wall with both loadbearing and energy-consuming functions,which has good application prospects in engineering.In engineering design,due to the complex geometry of corrugated steel sheets and the limitations of existing structural design software,finite element modeling cannot be well performed.Therefore,based on the force characteristics of nonbuckling corrugated steel wall,a variety of different simplified analysis models based on link elements are proposed.The horizontal axial link element model selected by comparative analysis is used as a simplified analysis model of corrugated steel shear wall.The principle of model parameter determination is obtained.The simulation accuracy is evaluated by the general finite element analysis software Abaqus,and the universality of the simplified model is investigated by parametric analysis.Finally,the applicability of the simplified model in the steel frame-non-buckling corrugated steel shear wall structure is analyzed,and the correction method of the internal force of the edge member is given for the designer’s reference.
