［摘要］以双层钢板混凝土组合剪力墙的试验研究为基础，采用有限元软件ABAQUS建立双层钢板混凝土组合剪力墙的非线性有限元模型。通过考虑材料非线性和模拟加载全过程对钢板屈曲等受力性能进行分析。有限元分析结果与试验结果吻合较好。在此基础上，分析了影响双层钢板混凝土组合剪力墙承载力和变形能力的主要因素，包括轴压比、高宽比、混凝土强度、钢材强度和钢板厚度。结果表明：随着轴压比的增大，双层钢板混凝土组合剪力墙的极限承载力有所提高，但变形能力下降，随着高宽比的增大，双层钢板混凝土组合剪力墙的极限承载力降低，变形能力增加；随着混凝土强度的增加，双层钢板混凝土组合剪力墙的极限承载力提高，变形能力减小；随着钢材强度和钢板厚度的增加，双层刚板混凝土组合剪力墙承载能力和变形能力都明显增加。提出计算该类组合剪力墙压弯承载力简化计算公式，将该简化公式计算结果与试验结果进行对比验证，结果表明，该公式的计算精度较高，可用于双层钢板混凝土组合剪力墙压弯承载力计算。［关键词］双层钢板混凝土组合剪力墙; 有限元分析; 变形能力; 轴压比; 混凝土强度等级中图分类号：TU398 文献标识码：A 文章编号：1002-848X(2015)15-0070-06
Study on finite element analysis and design method of dual steel-concrete composite shear wallMa Kaize1, Liu Chao1，Liu Boquan1, Yan Hongliang2,(1 Department of Architecture Engineering, Chang'an University, Xi'an 710064, China; 2 Wuhan Hechuang Architectural Engineering Design Co., Ltd., Wuhan 430071, China)Abstract:Base on the experimental study of dual steel-concrete composite shear wall(DSCW), the finite element analysis software ABAQUS was performed to set up a nonlinear finite element model of DSCW structure.Mechanical properties of buckling of steel plates were analyzed by considering material nonlinearity and simulation of loading process. The finite element analysis results were in good agreement with experimental results. Based on the proposed model, main factors influencing bearing capacity and deformation capacity of the structure were analyzed including axial compression ratio, height-width ratio, concrete strength grade, steel strength and steel plate thickness. It is concluded that with the increase of axial compression ratio, the ultimate bearing capacity of DSCW increases but the deformation capability decreases. With increase of high-width ratio, the deformation capability of DSCW improves but the bearing capacity decreases. With increase of concrete strength grade, the bearing capacity of DSCW improves and the deformation capability decreases. The deformation capability and bearing capability of DSCW improve greatly with increase of the steel strength and steel plate thickness. The simplified formula for compression-bending capacity for DSCW was proposed and fitted well with the experimental results. The formula is good precision and can be used to calculate the compression-bending capacity of DSCW.Keywords:dual steel-concrete composite shear wall; finite element analysis; deformation capacity; axial compression ratio; concrete strength grade
