| Abstract | ||
| This research deals with the nonlinear finite element analysis of non-prismatic prestressed concrete double tee beams under flexure. The numerical analyses have been carried out on beams chosen from the available experimental studies. Two different setups were considered. Beams B2 and B3 were experimentally tested by Mohammed 2003 and meant to represent the case of a non-prismatic prestressed concrete double tee beam. Beam B3, in particular, represents a beam with a short span. Beam B2, on the other hand is a sample for a relatively long span beam. These two beams were tested up to failure. The finite element results are compared with the results of the available experimental tests. Parametric studies have been carried out throughout this study to investigate the effect of some important material and solution parameters on the numerical results. Effects of concrete compressive strength, amount of prestressing steel reinforcement, and initial prestressing forces are studied. A mathematical model suitable for the nonlinear analysis of prestressed concrete beams under monotonically increasing load is used. The validity, accuracy, and efficiency of the computational model are examined by comparing the finite element results with the experimental results. | ||
