Performance of Corrosion-Damaged HSC Beams Strengthened with GFRP Laminates
نویسندگان
چکیده
This paper presents the results of an experimental program conducted for evaluating the performance of corrosion damaged HSC beams strengthened with GFRP laminates. Five Beam specimens of size 150x250x3000 mm were caste and tested for the present investigation. One beam specimen was neither corroded nor strengthened to serve as reference. Two beams were corroded to serve as corroded control. A reinforcement mass loss of approximately 10 and 25% were used. The remaining two beams were corroded and strengthened with GFRP. The study parameters included first crack load, first crack deflection, yield load, yield load deflection, service load, service load deflection, ultimate load and ultimate deflection. Based on the results it was found that the UDCGFRP laminated beams showed distinct enhancement in ultimate strength and ductility. Keywords—Corrosion, high strength concrete, strengthening,

متن کاملUltimate Tendon Stress in CFRP Strengthened Unbounded HSC Post-Tensioned Continuous I-Beams
The use of unbounded tendons is common in prestressed concrete structures and evaluation of the stress increase in unbonded tendons at ultimate flexural strength of such structure has posed a great challenge over the years. Based on the bending experiment for two-span continuous post-tension beams with unbounded tendons and externally applied CFRP sheets, the monitoring of the stress increment ...
