Abstract

Studies have shown that one of the leading causes of earthquake inflicting irreparable damage has been the high weight of structures. Using FRP composite sheets-due to the proper mechanical and physical properties to reinforce and improve concrete members in load-bearing, removal of concrete in the deflection and increasing the ductility of concrete-is an appropriate option. The purpose of this study is to strengthen voided concrete slabs with AFRP, CFRP and GFRP. In this study, 10 specimens of reinforced concrete with dimensions of 150×70×20 cm were investigated. The results demonstrated that the amount of load capacity in the Network strengthened specimen with CFRP compare to the control sample 175% and, in Linear, strengthened specimen with AFRP in comparison with the control sample 153% increased. This value in comparison with Solid specimens increased by about 96% for samples having been strengthened with CFRP and 91% for those strengthened with AFRP. The maximum displacements have been presented in the specimen strengthened with CFRP (236%) compared to that of the control sample and in the specimen strengthened with GFRP (99%) compared to that of the control sample. The stiffness amounts in Linear specimen strengthened with CFRP 225% compared to that of the control sample and in Network specimen strengthened with AFRP 136% compared to the that of control sample also increased.
