ABSTRACT

In this study is investigated the performance of different glass fibre-reinforced polymer strengthening schemes on infilled reinforced concrete (RC) frames. The main objective was to limit the damage to beam–column joints and inter-storey drift ratios and to protect RC frames against the negative effects caused by infill-RC frame interaction. Five specimens were tested: one without infill and four infilled with full-scale hollow clay block masonry unit, three of which were strengthened with different schemes. Results showed that the beam–column joints could remain undamaged, lateral strength and stiffness were enhanced, inter-storey drift was limited, and new load carrying systems are generated.

摘要

在这项研究中，研究了不同玻璃纤维增​​强聚合物加固方案在填充钢筋混凝土 (RC) 框架上的性能。主要目标是限制对梁柱接头和层间漂移比的损坏，并保护钢筋混凝土框架免受填充钢筋混凝土框架相互作用造成的负面影响。测试了 5 个试件：1 个无填充，4 个填充全尺寸空心粘土砌块砌体，其中 3 个采用不同方案加固。结果表明，梁柱节点保持完好无损，横向强度和刚度得到提高，层间漂移受到限制，并产生了新的承载系统。
