Influence of boundary conditions on the state of stress and strain in deep girder

The analysis of stresses and strains in two reinforced concrete deep girders was performed theoretically, applying the finite element method, whereas the experimental part, i.e. the structures' models testing were undertaken in the laboratory. Reinforced concrete deep girder M1 38 cm thick, is relied on reinforced concrete pillars which are fixed into the base. Another reinforced concrete deep girder M2 38 cm thick, is rigidly fixed into the base.The results analysis of conducted investigations for two reinforced concrete deep girders (M1 and M2) indicated that the differences in stresses amounted even up to 18%, and in displacements up to 16, 7%. A deep girder with the columns (M1) is a better solution for the construction than the deep girder (M2) rigidly fixed into the base.
