摘要

本研究对基于NBR 6118(2014)尺寸的钢筋混凝土梁与基于ACI 440.1R(2015)尺寸的玻璃纤维增强聚合物(GFRP)钢筋加固梁进行了四点弯曲试验对比试验分析。梁的尺寸是为了抵抗相同的力，并满足使用极限状态(SLS)。结果表明，在SLS-DEF之前，两组梁的竖向位移行为相似，而GFRP梁的挠度更大。在极限荷载下，带有玻璃纤维杆的梁的阻力比带有金属杆的梁高约64%。

Flexural behavior of concrete beams reinforced with glass fiber reinforced polymer and steel bars

In this study, a comparative experimental analysis is performed between steel-reinforced concrete beams, which are dimensioned based on NBR 6118 (2014), and beams reinforced with glass fiber-reinforced polymer (GFRP) rebar, which are dimensioned based on ACI 440.1R (2015) after being subjected to a four-point bending test. The beams are dimensioned to resist the same force and to satisfy the service limit state (SLS). Results show that the two groups of beams exhibit similar vertical displacement behaviors until the SLS-DEF, whereas the GFRP beams exhibit larger deflections. At the ultimate load, the beams with fiberglass bars indicate a higher resistance by approximately 64% compared with those with metal bars.

期刊介绍： The Journal of Construction is aimed at professionals, constructors, academics, researchers, companies, architects, engineers, and anyone who wishes to expand and update their knowledge about construction. We therefore invite all researchers, academics, and professionals to send their contributions for assessment and possible publication in this journal. The publications are free of publication charges. OBJECTIVES The objectives of the Journal of Construction are: 1. To disseminate new knowledge in all areas related to construction (Building, Civil Works, Materials, Business, Education, etc.). 2. To provide professionals in the area with material for discussion to refresh and update their knowledge. 3. To disseminate new applied technologies in construction nationally and internationally. 4. To provide national and foreign academics with an internationally endorsed medium in which to share their knowledge and debate the topics raised.
