摘要
通过用数值计算程序算得 16个不同宽厚比和强度比的典型截面的弯矩—轴力曲线 ,采用曲线拟合的方法提出了方钢管混凝土截面强度的计算方法 ,计算值与试验结果吻合较好。
Base on the M N relationship of 16 representative concrete filled rectangular steel tube column (CFRTC) cross section with different D/t ratio and f c/ f y ratio by numerical computation,the calculating method of CFRTC cross section strength is derived by curve fit method.The results obtained by the proposed method are in good agreement with the experimental ones.
