Abstract
Although the seismic behavior of moment-resisting frames (MRFs) reinforced with conventional steel has been extensively studied, the performance of MRFs that are reinforced with alternative materials, such as glass fiber–reinforced polymers (GFRPs) is not fully explored. The presence of floor slabs, integrally cast with beams, is one of the main factors that affects the seismic behavior of GFRP-reinforced concrete (RC) MRFs, which is still uncovered. To fill this gap, three full-scale assemblies, one beam-column and two beam–column–slabs, were constructed and tested to failure under reversal quasi-static cyclic loading. The main test parameters were the presence of slabs and type of reinforcement (steel and GFRP). Moreover, a series of finite-element models were developed and used to investigate the effect of slab width and lateral beam size on the contribution of slabs. Test results indicated that GFRP-RC slabs, when in tension, significantly contribute to the moment capacity of beams. It was also observed that the presence of slabs increases the initial lateral stiffness of GFRP-RC MRFs, which can reduce lateral deformations of the frames during earthquakes.
