Abstract

This paper presents an investigation conducted on repairing damaged Reinforced Concrete (RC) beams with a large rectangular web opening using externally bonded plates. Carbon Fiber Reinforced Polymer (CFRP) and steel plates were used as repair materials with two types of configuration hexagonal and rectangular for each material. The beams contain a rectangular web opening at one of the shear spans. The externally bonded CFRP sheet and steel plate were found to be effective in repairing RC beams with a large rectangular web opening. The results showed that CFRP plates perform better than steel plates and that the rectangular configuration is better than the hexagonal one.

碳纤维布与钢板复合修复带腹板开口破损钢筋混凝土梁的效果

本文介绍了采用外粘接板修复大矩形腹板开口钢筋混凝土梁的试验研究。采用碳纤维增强聚合物(CFRP)和钢板作为修复材料，每种材料有六角形和矩形两种构型。梁包含一个矩形腹板开口在一个剪切跨度。结果表明，CFRP板与钢板外粘接是修复矩形大腹板梁的有效方法。结果表明，CFRP板的性能优于钢板，矩形结构优于六角形结构。
