摘要:
对偏心受压PVC-FRP管钢筋混凝土柱破坏机理进行分析,根据弹性理论,将PVC-FRP管等效为双向复合材料管,利用应变协调条件,得出PVC-FRP管对核心混凝土紧箍力的计算方法.在此基础上,根据极限平衡条件,推导出偏心受压PVC-FRP管钢筋混凝土柱承载力的计算公式.并将计算值与试验结果进行比较,验证了理论公式的正确性.该研究为复杂应力状态下PVC-FRP管钢筋混凝土柱的受力性能分析提供理论依据.
Abstract:
The failure mechanism of PVC-FRP confined reinforced concrete column under eccentric compression is analyzed in this
paper.According to the elastic theory, PVC-FRP tube can be equivalent to the two-way composite tube, using strain coordination
conditions, a calculating method for the hoop force exerted by PVC-FRP tube to core concrete is obtained. On the basis of the limit
equilibrium theory,the calculation formula of bearing capacity of PVC-FRP confined reinforced concrete column under eccentric
compression is deduced. The calculated values of proposed model agree well with experimental results. This paper presents theoretical
basis for the mechanical properties of PVC-FRP confined concrete column under complex stress state.
