Abstract: Earlier proposals for shape factors used in calculations of bearing capacity of square and rectangular footings are examined. gTwxmp.,
These proposals are based on empirical data for small footings, whereas a new suggestion for these factors presented in this paper is based 5b-: e? |
on the elasto-plastic model of the soil and finite element analysis. The earlier factors modifying the contribution of cohesion and m\?H
<o0
overburden were found to be conservative, but acceptable in design. However, the earlier proposals for the shape factor that affects the Jp]eFaqp
contribution of the soil weight to the bearing capacity indicate contradictory trends, and the factor calculated in this paper is suggested as l]v>PIh~N
an alternative. Rjz~n38.
