N2 - This paper presents the results of an experimental study of structural lightweight concrete with glass fiber reinforcement (GFRP) bar for prefabricated single footing. In this study, seven full scale concrete single footings specimens, which were reinforced by GFRP bar located on a bed of soil, were tested. One of the specimens was made of normal weight concrete and the others were made of structural lightweight concrete. Four of the lightweight footing specimens contained polymer fibers. Also, two of the lightweight footing specimens contained shear reinforcement. Results indicated that the maximum GFRP strain on normal weight and lightweight concrete footing with polypropylene fibers are about 55 and 23% of the ultimate strain, respectively. Furthermore, adding polypropylene fiber and shear reinforcement enhanced the structural behavior of footings and limited the extent width of cracks which was wider in lightweight footings than that of normal weight concrete.
