Abstract: In this paper, a nonlinear finite element methods developed to analyze and study the behaviors of Unbonded Prestressed Concrete (U. P. C) beam. The author adopts various material analysis mcxiels, makes a program by means of finite element method to analyze U. P. C test beams. The results of finite element analysis well agree with those of test beams. By analyzing some factors which are considered to influence ultimate flexural strength and shear strength of U. P. C beam, puts forward a practical calculation formula.

Key words: unbonded partially prestressed, nonlinear finite element, flexural strength, shear strength
