Abstract This study presents the evaluation of various structural analysis approaches to theoretically determine the bending resistance of flexural reinforced concrete elements strengthened with textile-reinforced mortar (TRM), which are gaining more and more attention as external strengthening layers. To assess the increase in capacity due to strengthening, multiple experimental studies from the literature were evaluated. Different structural analysis approaches for determining the flexural strength increase were tested against the experimental data. Finally, the consideration of strain limits for the textile layers, as also applied in the dimensioning of externally bonded fiber-reinforced polymers, proved to be the most reliable analytical approach.

确定用织物增强砂浆加固的钢筋混凝土构件抗弯能力的结构分析方法的适用性评估

摘要 本研究提出了对各种结构分析方法的评估,以从理论上确定用织物增强砂浆 (TRM) 加固的受弯钢筋混凝土构件的抗弯性,其作为外部加强层越来越受到关注。为了评估因强化而增加的能力,对文献中的多项实验研究进行了评估。针对实验数据测试了用于确定抗弯强度增加的不同结构分析方法。最后,对纺织层的应变限制的考虑,也应用于外部粘合纤维增强聚合物的尺寸设计,被证明是最可靠的分析方法。
