Abstract
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.
