摘要：
Non-linear finite element model of prestressed steel reinforced concrete(PSRC) beams were carried out by using software ABAQUS. The effects of the parameters of non-prestressed reinforcement ratio, prestressed reinforcement ratio, effective prestressed force and non-prestressed tendons yield strength on the ultimate strength and ductility of PSRC beam were investigated. It is found that increase of the tension reinforcement ratio has little impact on the ultimate deflection but can improve the ultimate capacity of PSRC beam. Increase of the prestressed steel ratio can significantly improve the cracking load, stiffness and ultimate capacity of PSRC beam. The effective prestressed force can improve the bearing capacity of PSRC beam.
