Behavior of Strengthened R.C Flat Slab with Different Shapes of Openings, with Fiber ReinforcedPolymers
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 6
Abstract
Several buildings, bridges, tunnels, and marine structures have already been strengthened and repaired in many countries such as Japan, Europe, USA, Canada, and Egypt using fiber reinforced polymers (FRP) [1]. FRP is also used in new structures, especially at bridges. Carbon Fiber Reinforced Polymers (CFRP) [2,3] used in special applications including radar stations; structures for magnetic levitation trains, antenna towers, and many n- structural elements. The objective of this research was to investigate the feasibility of strengthening of reinforced concrete flat slab with openings with different sizes using CFRP laminates under uniform distributed load. The study program was used to explore experimentally the effect of opening size on the behavior of CFRP strengthened of flat slabs. Three main groups were used in this Study, 1st group was flat slabs without opening and it's called reference group, 2nd group was flat slabs with opening in columns strips and without strengthened, 3rd group was flat slabs with openingon column strips and strengthened by CFRP. A comparison between ultimate loadsand displacements were done between three groups as well as crack shapes of three groups.
