dc.description.abstractThis research investigates the use of carbon fiber reinforced polymer (CFRP) sheet and bar in concrete to increase punching shear capacity. The study focuses on the use of 1000?1000?100 mm3 reinforced flat plates and their flexure in both directions. The flat plates are subjected to a single-point load and a column stub. CFRP has a high modulus of elasticity and low coefficient of thermal expansion. Fifteen reinforced concrete flat plates were investigated, with three without FRP as control flat plates and twelve divided into two groups. The results showed that using CFRP composites to reinforce slabs at columns postponed the first slab flexural fractures, resulting in an increase in slab 2's ultimate punching shear capacity of 127.4 kN to 141.2 kN and a rise in sustained deflection from 33 mm to 46 mm. Strengthening slabs with CFRP delays the onset of concrete cracking and increases the initial slab stiffness by about 20% compared to an non-reinforced slab. Ultimate punching shear capacity improved using CFRP, making it on par with the slab without apertures. This research highlights the importance of using CFRP in concrete manufacturing systems to prevent failures and ensure long-term stability. ? 2024 The authors.
