Prediction of static behavior for SFRC deep beams using new and simple nonlinear models
Journal Title: Caspian Journal of Applied Sciences Research - Year 2012, Vol 1, Issue 5
Abstract
The presence of steel fiber in the concrete deep beam will improve its deformation characteristics and shear capacity. Deep beam is a structural element in which the strain distribution is considered nonlinear. The using of new steel fiber concrete behavior nonlinearities in the prediction of static behavior of steel fiber reinforced concrete (SFRC) deep beam has not been studied extensively. In the present endeavor, novel and simple nonlinear mathematical relationships have been formulated depending on many experimental data. These relationships were used to develop new analytical computer program coded in FORTRAN with employing Heterosis finite elements to investigate deep beam behavior. Present results show good agreement with other related studies outputs in terms of deflections, applied loads, strains and failure pattern.
