Bearing Capacity Factors of Flat Base Footing by Finite Elements

This paper presents the computations of vertical bearing capacity factors Nc, Nq, and Nγ, of the smooth and rough strip, circular and ring footings resting on soil with a friction angle (�) ranging from 5° to 45° using a finite element viscoplastic strain method obeying the Mohr-Coulomb yield cr...
