摘要:
为了研究钢筋混凝土(RC)空心柱在不同参数下的破坏机制和力学性能,本文采用基于Matlab的非线性数值计算,分析空心柱在不同参数下的力学性能。采用基于ABAQUS的有限元模拟与之对比,分析空心柱在不同轴压比、高宽比、壁宽比、配箍率、纵筋率下的力学性能。结果表明:随着轴压比的提高,空心柱水平承载力先增加后减小,在轴压比为0.4时承载力达到峰值,高宽比、壁宽比、配箍率、纵筋率对空心柱的力学性能和破坏模式有较大影响,研究结果给实际工程设计及应用提供参考。
Abstract:
To study the failure mode and mechanical properties of reinforced concrete(RC)hollow columns with different parameters,the RC hollow columns under static horizontal loads were simulated using nonlinear analysis program Matlab and finite element software program ABAQUS.The accuracy of the simulated was verified by the comparison between the results of Matlab analysis and Abaqus.Some parameters including the axial-load ratio,height-width ratio,width-thickness ratio,reinforcement ratio,stirrup ratio are studied.The results showed that the horizontal bearing capacity of hollow columnin creased at beginning with the increase of axial-load ratio,but when the ratio reached 0.4,the capacity declined as following.The height-width ratio,width-thickness ratio,reinforcement ratio,stirrup ratio had a great influence on the seismic performance and failure mode,which provided reference for practical engineering design and application.
