【 摘 要 】

Prestressed steel reinforced concrete beam(PSRCB) is a new type prestressed composite beam which uses prestressing technology in steel reinforced concrete beam (SRCB). The complete failure procedure of PSRCB was analysised by three-dimensional nonlinear finite element method. Numerical results agree well with experimental results. Then the numerical model was used to conduct some parametric studies including tensile rebar ratio, concrete compressive strength, H-section steel ratio, effective stress of prestressing strands and degree of prestressing.
