FRP加固框架节点的受力影响因素的数值模拟

摘要

FRP (Fiber Reinforced Plastics) fiber reinforced concrete frame joints was carried out a numerical analysis with finite element analysis software RFPA (Realistic Failure Process Analysis).It explored the effect of reinforcing from the concrete strength,fiber paste length and thickness.Finite element analysis results show that the reinforcement of the frame joints withstand the load and deformation capacity has improved signifi-cantly.%利用有限元分析软件RFPA （Realistic Failure Process Analysis）对FRP （Fiber Reinforced Plastics）纤维加固混凝土框架节点进行了数值分析，从混凝土强度、纤维布粘贴长度、纤维布粘贴厚度三方面探讨对加固效果的影响。有限元分析结果表明，加固了的框架节点所能承受的荷载和变形能力都有了显著提高。
