By means of nonlinear finite element analysis, the stress distribution in wall foundation under columns is studied. The stress dispersion in the area under a column is studied specially. A design accommendation for reinforcement in underground wall is presented in this paper according to the calculation results.
Keywords: wall foundation; reinforced concrete; finite element
