PARAMETRIC ANALYSIS OF MID-SPAN DEFLECTION OF PRE-STRESSED STRENGTHENING RC BEAMS WITH HFRP

Through establishment of FE model,the mid-span deflections of RC beams strengthened by Pre-stressed HFRP are parametric analyzed under the conditions of different load cases,different Young's modulus and thickness of adhesive, different style of strengthened,different prestressing force.The results show that the mid span deflection of RC beams is reduced by strengthened with pre-stressed HFRP which improve the strengthening effect.
