ETUDE TRIDIMENSIONNELLE DE LA CAPACITE ULTIME DES PLAQUES D’ANCRAGE DANS UN SOL FROTTANT

Abstract

Plate anchors are generally square, circular or rectangular. This study focuses on a numerical study using the finite-difference code Fast Lagrangian Analysis of Continua in 3 Dimensions (FLAC3D), to evaluate the ultimate pullout capacity of horizontal circular anchors plate embedded in a frictional soil. The soil was considered to be a linearly elastic-perfectly plastic material, obeying Mohr–Coulomb criterion. The anchor break-out factors were calculated for a rigid and rough circular plate, subjected to centered vertical loads. The results have been compared with those available in the literature
