CFRP加固偏压H型钢柱承载力数值模拟分析

Numerical simulation analysis of bearing capacity of CFRP reinforced biased h-shaped steel column

文章设计了6根H型钢柱构件,以CFRP粘贴层数、偏心距为参数,对H型钢柱进行了有限元数值模拟分析。通过建立"实体-壳"模型进行模拟,简述了模型单元的选取、边界条件的设定等,最终计算得出了构件的极限稳定承载力、荷载-位移曲线等重要数据,通过对比分析,得到了参数对极限稳定承载力的影响。

In this paper,six H-shaped steel column members are designed,and the number of CFRP adhesive layers and eccentricity are used as parameters.The H-shaped steel columns are numerically simulated and analyzed.Through the establishment of a“solid-shell”model for simulation,the selection of model elements,the setting of boundary conditions,etc.are briefly described,and finally the important data such as the ultimate stable bearing capacity of the member and the load-displacement curve are obtained.Through comparative analysis,the influence of parameters on the ultimate stable bearing capacity is obtained.
