摘要
以有限单元法和钢结构稳定理论为基础,运用ANSYS有限元软件进行计算与分析,研究碳纤维对受循环荷载作用的钢构件的增强作用。研究发现:轴压比是影响受压钢构件滞回性能和碳纤维使用效果的重要因素;增强后钢构件的循环水平极限荷载和位移延性会随着碳纤维用量的增长而增大。粘贴碳纤维能够有效地提高钢构件的承载力,改善钢构件的延性,提高其抗震性能。
The strengthening effect of carbon fiber on the steel member is studied, based on the finite element method and steel structure stability theory, using software ANSYS hysteretic behavior. The results show that the ratio of axial compression stress to strength is an important influence factor to the hysteretic behavior of compressed steel member and the using effect of carbon fiber, it is also show that the improvement of cycle horizontal critical load and displacement ductility of steel member are enhanced with the increase of the thickness of the carbon fiber, moreover, the aseismatic capacity is improved.
