摘要
基于简化修正压力场理论(SMCFT),考虑锈蚀后梁的保护层变化、箍筋的锈蚀率和屈服强度等方面的修正,收集并整理了现有文献中的纤维增强复合材料(FRP)加固锈蚀箍筋混凝土梁的58组试验数据以及3个计算模型,结合已有试验结果对比分析,证明本文模型的计算值与试验值比值的平均值和方差最小,体现了该FRP加固锈蚀箍筋混凝土梁计算模型的有效性。
A calculation model of shear capacity for the rust steel-stirrup reinforced concrete beams strengthened with fiber reinforced polymer(FRP)was proposed based on the simplified modified compression field theory(SMCFT),which is considered a few important factors of the existing experiment results,the change of protectiveness of the rust beam,the corrosion rate and yield strength of stirrups etc.Then,58 groups of test data and three calculation models are collected and analyzed from FRP strengthened rust steel-stirrup reinforced concrete beams are collected and analyzed from of the existing literature.It is proved that the average value and variance of the ratio between the calculated values and the test values of the proposed model in this paper are the smallest,which reflects that the validity of the proposed calculation model for the rust stirrup concrete beam strengthened with FRP.
