The present study examines the potential of using carbon fiber reinforced polymer (CFRP) strip technique in
\nrepairing or strengthening of preloaded, cracked, reinforced concrete one-way solid slabs. The reinforced concrete
\n(RC) slabs specimens were casted with dimensions of 1400×450×90 mm. Totally, seven specimens are tested,
\nincluding one reference specimen without strengthening and six specimens strengthening with CFRP strips. CFRP
\nstrips are placed along the slabs with different lengths and configurations. Before strengthening, The slabs were
\npreloaded to level of 60% from the ultimate load capacity of the slabs. Length and configuration of CFRP strip are
\nthe main parameters that are investigated in this experimental research. The strengthening slabs are divided into two
\ngroups according to configuration of CFRP strip, each group consist of three slabs, in both groups, effect of length
\nof CFRP strip using three lengths (600mm, 800mm and 1000mm) was studied, but in the first group one segment of
\nCFRP strip with (100mm) width was used , while in the second two segments of CFRP strip with (50mm) width
\nwere used. The slabs were loaded under two point static load up to failure and the structural response of each slab
\nspecimen was investigated in terms of the onset of cracking, deflection, ultimate load and failure mode. The
\nefficiency of using CFRP strips technique to repair or strengthening and their effects on the structural behavior of
\ncracked concrete slab had been analyzed. It was observed that the strengthening technique used in this study is affect
\nthe load carrying capacity, deflection, stiffness, concrete compressive strain, cracking load and crack width of the
\nslab. This repair or strengthening technique was found to be able to restore and enhance the structural capacity of
\ncracked concrete slabs.<\/p>\n
