The structural performance of slab reinforced with steel and GFRP bars subjected to static and static cyclic load

ABSTRACT The FRP composite has recently emerged as a promising alternative material in the construction industry. The need for lightweight materials with excellent tensile strength and good corrosion resistance has increased focus on composites reinforced with natural or synthetic fibers. This study focuses on the experimental study of slab size 600 mm × 450 mm × 50 mm with GFRP bars to replace conventional steel bars. The study examined the short-term behaviour of slab specimens with glass fiber-reinforced polymer bars and conventional steel bars subjected to static and static cyclic loadings. A comparative study is also done. The results are presented, discussed and compared the deflection, load-carrying capacity, strain distribution, cracking moment and failure mode, etc. The study concluded that the slab reinforced with GFRP bars shows 3.6% higher load-carrying capacity and 34.6% higher deflection than the traditional steel bars under static loading condition. The static cyclic loading condition shows 5.5% higher load-carrying capacity and 33.6% higher deflection in the GFRP bar reinforced slab than the conventional steel bar slab. The results show that the slab with GFRP bars resists higher load than conventional steel bars.
