摘要
为了便于计算双跨工字型连续钢梁的弹性临界弯矩,基于各种荷载形式下简支钢梁的临界弯矩计算公式,采用ABAQUS有限元分析软件对双轴对称工字型两跨连续钢梁与相应简支钢梁的临界弯矩进行了分析对比,拟合出了双跨连续钢梁临界弯矩的修正系数,得出了双轴对称工字型双跨连续钢梁的临界弯矩计算公式。
In order to easily calculate the elastic critical moment of a double span steel beam,comparing the critical moment of the continuous steel beam and the simply supported steel beam by the ABAQUS finite element analysis software,fitting out the critical moment coefficient,obtaining the formula of the critical moment.
