dc.description.abstractThe flexural behaviour of reinforced concrete (RC) slabs strengthened with carbon fibre reinforced polymer (CFRP) laminates is analytically addressed in this work. Analytical approaches are developed for (i) near-surface mounted (NSM), (ii) externally bonded reinforcement (EBR), and the EBR prestressed using (iii) mechanical anchorage (MA) and (iv) gradient anchorage (GA) systems. The analytical results show a good agreement with those from experimental program. Besides, the performance of two existing formulae for predicting the mid-span deflection is assessed, and the performance of the recent fib Bulletin 90 technical report for predicting the ultimate capacity of the strengthened RC slabs is appraised.por
