Nonlinear Finite Element Analysis Of Prestressed Concrete, Akram Shaker Mahmood, Mohamed N. Mahmood
Akram Shaker Mahmood
In the present study a nonlinear finite element analysis is carried out on twenty prestressed concrete cantilever beams having different lengths vary from 1.0m to 3.0m with 0.5m increments and subjected to a concentrated torque at the free end using ANSYS V10 finite element package. This study emphasizes on the effect of beam length to depth ratio on the strength, behavior of prestressed concrete beams and effectiveness of prestressing strands in the pre and post cracking stages of loading. This work is part of a PhD research program at the University of Mosul to investigate the non-linear three dimensional behavior …

This paper presents results from a nonlinear finite element analysis of a hybrid reinforced concrete rectangular section beams. The concept of hybrid R.C. concrete structures was applied in many designers for using in constructions of bridge superstructure. Although using the steel reinforcements are often modeled as a linear-elastic material until failure, the linear finite element analysis could not predict the behavior of the R.C. concrete beams model up to its failure. The materials, loadings, section properties with boundary conditions are taken from reference [Ref.3]. Results from material tests and loading tests of beams model indicated that the nonlinearity of concrete …
