| Abstract | A mat on piles has frequently been used as a foundation for a heavily loaded structure
on soft soils, when the mat has inadequate load carrying capacity, or when an excessive
settlement will arise. In this study, the behavior of vertically loaded mat supported on piles is
analysed using a finite element method. The mat is modelled as thick plate element based on
the Mindlin plate theory, and the piles are represented by linear elastic spring elements. Nine
node bilinear plate elements based on an as~umed strain method is employed for bending element
~ecause of the excellent characteristics in convergence, and the spring constant is derived from
load settlement curve. The effects of mat-soil interaction and pile group interaction are assumed
negligible. Bending moments and shear forces are compared with conventional rigid method
and the sensitivity of stress resultants on some parameters is considered by the proposed finite
element method. It can be concluded that the conventional rigid method may underestimate
the stress resultants. |
