| 摘 要： | 采用灰色系统理论的关联分析方法,对已有17组预应力CFRP布加固RC梁的实验数据进行关联度计算,分析碳纤维布配布量、梁截面高度、钢筋配筋率、预应力度、混凝土强度和碳纤维布抗拉强度等参数对加固梁抗弯承载力的影响。结果表明,上述影响参数对加固梁的抗弯承载力影响程度依次递减。本文构建了一个考虑影响参数组合权系数的预应力CFR...

| Abstract: | Based on 17 groups of test data on flexural capacity of prestressed carbon fiber reinforced plastics(CFRP) strengthened RC beams,the technique of analyzing the influence parameters on flexural capacity using grey relational method is presented in this paper.The influence parameters include CFRP amount,beam height,reinforcement ratio,prestressing degree of CFRP,concrete strength and fiber tensile strength.The results of grey relational analysis indicate the influential order of above parameters is gradually ... |
