冲击荷载对FRP布加固RC圆柱力学性能的影响
Effects of impact load on mechanical performance of RC circular columns reinforced with FRP wraps
摘要
Abstract
This paper aims to address the insufficient demand space due to the usable space reduced caused by the installation of anti-collision devices around columns in underground garages and multi-story parking lots,and proposes a reinforcing solution to RC(Reinforced Concrete)columns by using FRP(Fiber Reinforced Polymer)fabric.The study involves investigate the impact of different layers of Basalt Fiber Reinforced Polymer(BFRP)fabric on column performance under the impact loads with ABAQUS finite element software;and comparing and analyzing the reinforcement effects on the composite columns with BFRP fabric and Carbon Fiber Reinforced Polymer(CFRP)fabric.The research results indicate that two layers of BFRP fabric for reinforcement can balance safety and cost-effectiveness as the impact velocity less than 16 m/s.Compared to CFRP fabric,BFRP fabric exhibits superior performance in resis-ting impact loads and can serve as a viable alternative instead of CFRP fabric for component reinforcement against impact loads.关键词
