摘要
以有限单元法和钢结构稳定理论为基础,运用大型ANSYS软件进行计算与分析,研究碳纤维增强复合材料(CFRP)对钢框架承载力的增强作用。研究结果表明:CFRP增强后的钢框架,其承载能力和位移延性的提高程度随着CFRP用量的增长而增大。粘贴CFRP能够有效地提高钢框架的承载能力,改善钢构件的延性。
In order to study the strengthening effect of CFRP on the steel frame, this paper based on the finite element method and steel structure stability theory , using the big computer software ANSYS to calculate and analyze. The results show that the bearing capacity and ductility of steel frame strengthened with CFRP have been enhanced obviously. Moreover, with the thickness of the CFRP increasing, the effects of strengthening become prominence.
