圆钢管混凝土桥墩弯矩-曲率关系分析
|
摘要
依据2个常用的钢管混凝土材料本构模型,采用纤维模型法编制了MATLAB计算程序,以分析钢管混凝土桥墩的截面弯矩-曲率关系。理论计算得到的弯矩-曲率关系曲线与国外学者进行的实验结果吻合较好,表明程序具有良好的适用性。并进一步分析了套箍系数、轴压比对钢管混凝土桥墩弯矩-曲率关系的影响。
According to two commonly used constitutive models of concrete-filled steel tube(CFST),a MATLAB program is coded by fiber model method in order to calculate the moment-curvature relationship of concrete-filled steel tube piers.It is proved that the program is serviceable through comparing theoretical calculations with experiment data.Based on the above summarizations,the effect of confining coefficients and axial load ratio on moment-curvature relation is analyzed.
