ABAQUS的内藏钢板剪力墙非线性仿真

Concealed steel plate shear wall of ABAQUS nonlinear simulation

为提高实际工程中剪力墙的抗震效果问题,采用ABAQUS有限元分析软件,建立了18个内藏钢板剪力墙模型,以轴压比、高宽比、钢板厚度为设计参数,在单调载荷作用下,对内藏钢板剪力墙的承载能力和变形特点进行分析.结果表明:轴压比增大,剪力墙的极限承载力就会跟着增大;高宽比大的剪力墙要比高宽比小的剪力墙的水平承载能力低;钢板厚度大的剪力墙抵抗侧向能力强.3个设计参数对内藏钢板剪力墙的承载能力和变形特点有一定的影响,为解决实际工程问题提供了理论依据.

To improve the aseismic effect of shear wall in practical engineering, by using ABAQUS finite element analysis software, this paper set up 18 concealed steel plate shear wall models, axial compression ratio, aspect ratio and steel plate thickness as the design parameters, under monotonic loading, bearing capacity and deformation characteristics of steel plate shear walls are analyzed. As the results show, increase the axial compression ratio, the ultimate bearing capacity of the shear walls will follow; Large aspect ratio of shear walls are lower than the small aspect ratio of small shear wall on bearing capacity; Larger thickness of the shear walls have strong ability to resist horizontal. Three design parameters bearing capacity and deformation characteristics of steel plate shear wall has certain influence, which provides a theoretical basis for solving practical engineering problems.
