摘要
采用试验研究与理论分析相结合的方法对CFRP布加固预裂钢筋混凝土梁的抗裂性能进行了相关研究。探讨了CFRP布加固钢筋混凝土梁在短期荷载作用下裂缝的发展规律以及裂缝发展的影响因素;得到了CFRP布加固钢筋混凝土梁在短期荷载作用下的平均裂缝宽度与最大裂缝宽度之间的近似关系式。可为修订CFRP加固技术规程,完善加固设计方法,拓展加固技术提供参考。
Theoretical analysis and experimental analysis are combined to investigate the crack resistance of pre-splitting re- inforced concrete beams which were strengthened by the CFRP cloth, the crack law of development and the crack contributory factor of the reinforced concrete beams in the short-term load is di^u.~sed, and the relationship between the average crack width and the maximum crack opening about the the reinforced concrete beams in the short-term load function will be founded . All of those axe very useful to revises the CFRP reinforcement technology standard, consummates the method of reinforcement design- ing and develop the reinforcement technology in the future.
