| 中文摘要 | 通过运用通用有限元软件ANSYS建立有限元模型,对5个超高强度钢材焊接工形截面轴心受压柱的整体稳定受力特性进行有限元分析。详细地介绍了建立有限元模型的具体方法,给出了分析其整体稳定特性的求解全过程,提出了输入构件几何初始缺陷和模拟截面残余应力的方法。通过将有限元计算结果与相应的试验结果进行对比,验证了本文建立的有限元模型的有效性。计算结果还表明,残余应力的变化对超高强度钢材焊接工形截面轴心受压柱整体稳定承载力的影响较小。; The finite element analyses(FEAs) were performed using the general software ANSYS for the overall buckling behaviors of the 5 ultra-high strength steel welded I-seetion columns under the axial compression.The building procedure of the FEA model and the solution programs were introduced in detail.The method to simulate the initial geometric defects and the residual stresses in the cross-sections were proposed.The effectiveness of the performed FEA was verified by the comparison between the FEA results and the test results.The FEA also indicated that the residual stress only has little effect on the overall buckling resistance of the ultra-high strength steel columns.; 国家自然科学基金项目(50708051); 长江学者创新团队发展计划项目(IRT00736) |
