现役混凝土板梁预应力碳纤维板加固效果研究

摘要

针对采用预应力碳纤维板材加固的现役开裂钢筋混凝土板梁开展静载试验研究和有限元分析,研究预应力碳纤维板材加固法对提高钢筋混凝土板梁的承载力、抑制裂缝发展的作用,并与常规加固方法比较,验证该加固方法的效果及其优势.%This paper focuses on the difference before and after reinforcement with prestressed carbon ifbre reinforced polymer strengthening which used in the active concrete plate beam with crack, to study the effect of prestressed carbon fibre reinforced polymer strengthening technique for bearing capacity increasement and crack decrease of concrete plate beam by static damaged test and FEM analysis, and compared with the result of conventional reinforced method, to verify the effect of this reinforced method and its advantages.
