Abstract

The main aim is to examine the behavior of laminated carbon fiber and glass fiber reinforced polymer (CFRP) and (GFRP) reinforced composite (RC) beams. The physical characteristics of these laminates, such as tensile strength, modulus of elasticity and strain capacity are examined. The capacity of load bearing, deflection, and cracking behavior of RCC beam specimens along with various types and numbers of laminates will be analyzed and compared. The results will provide insight into the outcome of using different kinds of laminates over RCC beams and identify the optimal configuration for their reinforcement. The findings of this research paper will have significant implications for the construction industry, particularly for rehabilitation and repairing of old buildings and other structures. The use of CFRP and GFRP laminates as a reinforcement material can extend the life of RCC beams, reduce the need for costly repairs and replacements, and increase the safety and sustainability of infrastructure. The paper will conclude with recommendations for the optimal use of carbon fiber and glass fiber reinforced polymer laminates in RCC beam reinforcement, including the selection of appropriate materials and design criteria for their successful application.

CFRP和GFRP叠层混凝土梁的性能
主要目的是研究层压碳纤维和玻璃纤维增强聚合物(CFRP)和(GFRP)增强复合材料(RC)梁的性能。测试了这些层合板的物理特性,如拉伸强度、弹性模量和应变能力。将分析和比较不同类型和数量的碾压混凝土梁试件的承载能力、挠度和开裂行为。研究结果将深入了解在碾压混凝土梁上使用不同种类的层压板的结果,并确定其加固的最佳配置。这份研究报告的研究结果将对建造业,特别是对旧建筑物和其他构筑物的修复和维修产生重大影响。使用CFRP和GFRP层压板作为加固材料可以延长碾压混凝土梁的寿命,减少昂贵的维修和更换的需要,并增加基础设施的安全性和可持续性。本文最后将对碳纤维和玻璃纤维增强聚合物层压板在碾压混凝土梁加固中的最佳使用提出建议,包括选择合适的材料和成功应用的设计标准。
