摘 要: 钢板剪力墙在工程中的应用越来越广泛。在工程设计中,由于构件数量较大,采用复杂的精细有限元建模将使结构模型过于庞大,从而降低计算效率及工作效率。本文利用ANSYS有限元分析软件,针对传统平钢板剪力墙和加劲钢板剪力墙的两种常用简化分析模型——斜拉杆简化模型和各向异性板简化模型,通过与精细有限元模型结果进行对比,研究两种简化模型对新型波纹钢板剪力墙的适用性。结果显示,各向异性板模型可以较准确地模拟结构屈曲前的刚度特性,而斜拉杆模型对结构的模拟功能并不准确,因此波纹钢板剪力墙的简化分析模型不能直接利用平钢板剪力墙常用的简化分析模型,尚需进一步探究。

Abstract: Steel plate shear wall is widely used in high-rise buildings. In engineering design, due to the large number of components, complex finite element modeling will make the structural model too large, resulting in reduced computation efficiency and work efficiency. In this paper, the applicability of different simplified models for the analysis of new corrugated steel plate shear walls is explored by using the finite element analysis software ANSYS. The two simplified analysis models of the traditional flat steel plate shear wall and stiffened steel plate shear wall, corresponding to the diagonal strip model and the anisotropic plate model respectively, are mainly discussed in the paper. The applicability of the two simplified models is studied by comparison with the results of the detailed finite element model. The results show that anisotropic plate model can accurately stimulate the characteristic of stiffness before buckling of the corrugated panel, while the simulation of the diagonal strip model is not accurate enough. Therefore, the commonly used simplified analysis model can not directly be used to analyze corrugated steel plate shear walls and further exploration of the accurate and reasonable simplified model for this new type of steel plate shear wall is needed.
Key words: civil construction structure; simplified analysis model; finite element analysis; corrugated steel plate shear wall
