最近对土木工程基础设施的评估表明，其中大部分在不久的将来需要大修。这证明了创新的钢筋混凝土结构，特别是复合材料的修复和加固方法的发展。这些技术之一包括通过用复合材料外壳限制来加强柱。本文报道了关于这一主题的研究计划的结果，并集中在与碳和芳纶纤维板约束的方形和矩形柱的行为。一系列小尺寸试件的试验结果表明，约束提高了混凝土轴压柱的强度和延性。
Recent evaluation of civil engineering infrastructure has demonstrated that most of it will need major repairs in the near future. This justifies the development of innovative rehabilitation and strengthening methods for reinforced concrete structures, especially with composite materials. One of these techniques consists of strengthening columns by confinement with a composite enclosure. This paper reports the results of a research program on this topic and concentrates on the behavior of square and rectangular columns confined with carbon and aramid fiber sheets. Results from a series of tests on small-scale specimens showed that confinement increased the strength and ductility of the concrete columns loaded axially.
