It is shown herein that concrete beams may also be prestressed with carbon-fibre-reinforced polymers (CFRP). The test results show that the static fracture behaviour of such beams is almost identical to that of beams prestressed with steel. Not only statically determinate, but also statically ...
Two reinforced concrete beams and one prestressed concrete beam were designed and tested with the proposed maximum reinforcement ratios. The outcomes demonstrate the validity of the proposed formula.This is a preview of subscription content, log in via an institution to check access. ...
For post-tension prestressed concrete beams, both of tendons laid in metal duct and wrapped by plastic sheets are recognized as unbonded tendon by researchers, and the same equation is used to estimate the flexural strength. But the contacting conditions between tendon and its surrounding concrete ...

Results of tests on 18 full-size prestressed, pretensioned concrete tee beams representing one-half of a structural double tee section are reported. The variables investigated were opening size, location of opening along the span, type and amount of web shear reinforcement, and amount of primary ...

Uy and Craine [4] performed experiments on both conventional and prestressed steel-concrete composite beams under positive moment. The results showed that post-tensioning the composite beam increased the ultimate resistance in about 20%. They also developed a numerical model that was calibrated with ...
Shear Behavior of Concrete Beams Reinforced with High Performance Steel Shear Reinforcement Therefore, reduction in the reinforcement ratio of MMFX steel, did not affect the serviceability of these beams. Analysis shows that the ACI 318, CSA, and AASHTO LRFD design codes can closely predict the ulti...
