| Abstract: | In this paper, the deflection, stress, crack characteristics and failure state of apreflex composite beam are studied by means of model test and the nonlinear FEM analysis. In thenumerical computations considered are the prestress losses of the first phase concrete caused byconcrete creep. The computation results are in good agreement with the test values. |
