Theoretic research on friction loss in post-tensioned prestressed concrete simply supported beam
Translated Abstract
According to the two distributed pattern including of continuous type and sectional type of the post -tensioned prestressed concrete simply supported beam , consider bending channel of the radial pressure p is nonlinear .The frictional resistance formula is deduced under arbitrary stress distri-bution using coulomb friction law .Through the example analysis , it shows that friction loss value using the deduces formula in this paper is bigger than the value counted by standard formula , and the differ-ence between the two is greater with the prestressed curvature increases .The friction loss value of sectional type is different to the continuous type .The finite element simulation results and the related test results show that the deduces formula in this paper is more accurate , which is closer to the meas-ured values .
