Abstract
This paper reports the numerical analysis of several pile caps supported on one steel pile The variables studied were the column contact area the pile embedment into the cap and the presence of a bearing steel plate welded at the pile head The numerical analysis was based out from a three dimensional model set by the finite element method analysis The results showed that the pile embedment length has a great influence on the mechanical behavior of the reinforced concrete caps although this aspect has not been well explored analytically or experimentally yet In addition it was verified that the pile embedment length has influence over the stress flow and the ultimate strength of the cap The results also pointed out that a steel plate at the top of the steel pile may lead to a positive effect by improving the load distribution inside the pile cap
