Several experimental studies have been conducted to investigate the influence of fiber-reinforced polymer on confined columns. Most of these studies examine the effect of some variable parameters such as the spacing between strips, the number of layers, the initial strength of concrete and the degree of confinement. This paper is the result of an experimental study on the behavior of plain concrete cylinders (Ø160 × 320 mm) reinforced with carbon fiber-reinforced polymer (CFRP) layers. The main purpose of this work is to study the influence of strip width of CFRP composite used for reinforcement. Five series of tests were carried out under a cyclic and progressive axial compression loading to failure. Tests were carried out using a compression machine MCC8 of 3000 kN capacity with automatic data acquisition system. In this investigation, the stress–strain curves were plotted in order to determine the stress–strain relationships and to obtain the behavior of the concrete cylinders. In conclusion, it is evident that this study has shown an optimal configuration and an adequate distribution of CFRP composite materials to minimize the utilization of the latter and thus to use it to its ultimate strength and to carry out the ultimate limit state design as well.

碳纤维布条的宽度对普通混凝土圆柱体压缩性能的影响

已经进行了几项实验研究来研究纤维增强聚合物对受限柱的影响。大多数这些研究检查了一些可变参数的影响，例如条带之间的间距、层数、混凝土的初始强度和约束程度。本文是对用碳纤维增强聚合物 (CFRP) 层增强的素混凝土圆柱体 (Ø160 × 320 mm) 的行为进行的实验研究的结果。这项工作的主要目的是研究用于加固的 CFRP 复合材料的带材宽度的影响。五个系列的测试是在循环和渐进的轴向压缩载荷下进行的。使用具有自动数据采集系统的 3000 kN 容量的压缩机 MCC8 进行测试。在这次调查中，绘制应力-应变曲线是为了确定应力-应变关系并获得混凝土圆柱体的行为。总之，很明显，本研究显示了 CFRP 复合材料的最佳配置和适当分布，以最大限度地减少后者的利用率，从而将其用于其极限强度并进行极限状态设计。
