【摘要】 通过建立FRP加固RC梁的有限元模型,对预应力HFRP加固RC梁跨中挠度进行参数化分析,研究了不同荷载大小,不同胶层弹性模量及厚度、不同加固形式和不同预应力大小的作用下,RC梁跨中挠度的变化情况。结果表明:预应力HFRP可减小RC梁跨中挠度,并增强加固效果。更多还原

【Abstract】 Through establishment of FE model,the mid-span deflections of RC beams strengthened by Pre-stressed HFRP are parametric analyzed under the conditions of different load cases,different Young’s modulus and thickness of adhesive, different style of strengthened,different prestressing force.The results show that the mid span deflection of RC beams is reduced by strengthened with pre-stressed HFRP which improve the strengthening effect.更多还原
