Abstract

Abstract-Carbon Fiber Reinforced Polymer (CFRB) has been effectively utilized in structural engineering; particularly in strengthening structural members.The current study addressesthe utilization of CFRP in one way strips concrete slabs subjected to a two line static loading system. Two different CFRP techniqueshave been used: externally strengthening and near surface mounted (NSM) techniques. Four samples of one way reinforced concrete strips slabs strengthened byseveral CFRP systems have been tested. Analysis results indicated that the laminate plate CFRP system is more efficient than other techniques.The maximum load carrying capacity of a 1500mm reinforced concrete slab with 0.314 steel ratio has been increased largely by 671%. This technique of strengthening has resulted in a decrease in the RCS maximum deflection by about 21%. In addition, the stiffness of RCS has increased and failure due to deflection occurred at 1.75% of the span length.
