Seismic vulnerability assessment of strengthened Glass Fiber Reinforced Concrete (GFRC)
Abstract This paper presents the effect of using Carbon Fiber Reinforced Polymers (CFRP) as retrofitting material on seismic behavior of Plain Cement Concrete (PCC) and Glass Fiber Reinforced Concrete (GFRC). The experimental work was carried out in two steps. In first step, cylindrical specimens of size 150 mm × 300 mm were cast by using both PCC and GFRC. In second step, the specimens were wrapped by CFRP in three different patterns. All the specimens were tested under monotonic compressive loading. The test results were later used in the non-linear static cyclic analysis of reinforced concrete frame modeled in a finite element based analytical tool. Seismic vulnerability assessment was then carried out using a modified capacity spectrum method to develop analytical curves for the frames. The results showed significant improvement in seismic performance of frames strengthened by CFRP. Collapse hazard level for unconfined GFRC structure was increased by 20.73% as compared to unconfined PCC structure. There was 21 to 28% improvement observed in collapse hazard level in confined PCC structures as compared to their unconfined counterparts. However, confinement of GFRC structures resulted in only 8% increase in collapse hazard level as compared to unconfined GFRC structures.
