Resumo(s)
The finite element program mechpy, developed within the authors’ team, which implements the upper and lower bound theorems of limit analysis, is applied to the calculation of the bearing capacity of foundations on soft soils improved with reinforcement columns. The problem is analysed in two and threedimensions, considering the soil and the columns responding under undrained conditions, using different replacement area ratios and different column-to-soil shear strength ratios. The upper and lower bound results are found to be in a narrow range and in good agreement with experimental results found in the literature. A simple equation is proposed to evaluate the bearing capacity of soil reinforced with columns.
