| Abstract | ||
| A three-dimensional finite element computer program ( 3DMPCP ) has been developed to investigate the behaviour of prestressed reinforced concrete beams and to predict their ultimate loads. To verify the ability of this computer program in predicting the correct behaviour of prestressed concrete beams, analysis of a simply supported prestressed reinforced concrete tee beam was carried out. The beam section is 1.12 m deep, 2.44 m flange width and it is designed for a span of 32.3 m from support to support. The test load, 0.85(1.4 DL. + 1.7 LL.), was applied to the beam and flexural cracks were observed at midspan. The finite element analysis has indicated that numerical load-central deflection curve obtained is in good agreement with the experimental one. The analysis also gives the expectation for the ultimate load value. Distribution of concrete normal stress throughout a cross section and along the beam, at different stages of loading , are presented | ||
