Effects of Dimension and Boundary Condition of Columns in Rigidity of Reinforced Concrete Deep Beams

,Reinforced Concrete (RC) deep beams are a special type of beams due to their geometry, boundary conditions and behavior, compared to ordinary shallow beams. A lot of researches have been conducted on simply supported deep beams, but little study has been done on fixed-end RC deep beams. One of important stage for testing fixed-ended deep beams in laboratory is certainty about rigidity of supports. In this study deferent boundary conditions and dimension for columns of deep beams are modeled in a finite element program to obtain enough rigidity for fixed-end RC deep beam and finally suitable set up is suggested for testing fixed-ended concrete deep beam. The results indicate the effects of boundary conditions in rigidity of deep beam are more sensitive than the effects of size of columns.
