摘    要:钢结构中存在大量的受压构件,由于失稳而导致破坏。与传统的钢结构加固方法相比,FRP加固钢结构具有明显的优势。目前国内外对FRP加固钢结构技术的研究主要限于受拉构件和受弯构件加固,对受压构件的加固几乎还未涉足。采用能量法得到了FRP加固轴心受压钢管的弹性屈曲荷载,并与有限元计算结果进行了对比。

关 键 词:纤维增强复合材料  轴心受压  能量法  弹性屈曲荷载

Abstract:A significant number of steel structures are in service and many of th em failed due to buckling. There are several advantages of adhesively bonded fib er reinforced polymer (FRP) laminates to the deteriorated steel members over tradi tional retrofit methods. But currently limited research was conducted on tensile or bending steel members strengthened with FRP, and there was hardly any resear ch on axially loaded compression steel members. The elastic buckling load of axi ally loaded compression steel pipes strengthened with FRP was presented using energy approach. The analytical results were compared with those of the f inite element calculations.
Keywords:fiber reinforced polymers axially loaded compression energy ap proach elastic buckling load
