摘要

通过ANSYS软件模拟了单调荷载作用下钢筋混凝土试验框架柱的荷载—位移曲线,并与相应的试验结果进行比较分析.在有限元模拟试验框架柱的基础上,用ANSYS软件模拟了未做过试验的不同轴压比下的框架柱荷载—位移曲线.最后,根据ANSYS模拟的普通混凝土和高强混凝土框架柱的单调荷载—位移曲线,分析和讨论了箍筋形式、混凝土强度及截面形式等因素对轴压比限值的影响,从而确定出各种情况下的轴压比限值.
Load-displacement curves of reinforced concrete frame columns under laterally monotonic load were simulaed by ANSYS software in this paper,and the analysis results were compared with the experimental results.Based on the finite element model,the load-displacement curves of reinforced concrete frame columns with different axial compression ratios were obtained through the simulative analysis with ANSYS software.Lastly,the factors such as types of stirrups,strength of concrete,and sectional forms,etc.influencing the limit value of axial compressive ratio were analyzed and discussed,and then limit values of axial compressive ratio of frame columns in all conditions were obtained.
