摘要:
利用ANSYS有限元分析程序,对已有的型钢混凝土(SRC)试验柱的受力性能进行非线性数值模拟.介绍SRC柱单元建模和分析的方法,重点考虑SRC柱截面混凝土的区域划分及相应的应力-应变本构关系.通过对ANSYS的骨架曲线的讨论和分析,最终形成考虑不同混凝土约束区域的SRC柱数值模拟技术.采用提出的模型分析不同轴压比试件的P-Δ曲线,结果表明,除轴压比较大试件的分析结果与试验结果存在较大差异外,其他试件的P-Δ曲线与试验骨架曲线均吻合良好.
Abstract:
Nonlinear finite element analysis of five steel reinforced concrete(SRC) columns using the ANSYS software is conducted,and the mechanical behaviors of these columns are analyzed,which mainly focus on the numerical simulation of concrete stress-strain curves of these SRC columns and the division of SRC section.Based on the discussion of ANSYS skeleton curves,the technology to simulate SRC structures is finally established,which considers the different confined region of concrete.The P-Δ curves with various axial compression ratios are analyzed.The numerical simulation results are in good agreement with the experimental results except for the specimen with large axial compression ratios.
