In this study, the theoretical behavior of curved prestressed concrete beams have been investigated by using of three dimensional finite element method, in order to understand the behavior of this beam under incremental loads up to failure and also under long-term time conditions. Therefore, the analytical study have been done by parts: First part deals with short-term analysis, and other part deals with long-term analysis. This analysis is done by depending on package programs (ANSYS+CivilFEM V12.0  version 2009). Willam and Warnke models have used to represent the nonlinear behavior for concrete. The curved prestressed concrete beam represents by three dimensional model include of Isoparametric 8-Node Brick Element known as SOLID65 which is used in short-term analysis, while the Element known as SOLID185 have been used in long-term analysis. Due to the time-dependent effect on ultimate load value for concrete structures, both of the creep and the shrinkage effects on properties and behavior for concrete have been taken into consideration using finite elements technology dependence on recommendation committee of American Concrete Institute (ACI 209). Also, the  effective modulus approaches used in the representation of creep effect. Also, all the prestressed loss for prestress concrete members have been included.
