The investigation of load carrying capacity of elastic-plastic strain hardening bisteel i-section beams

Abstract

In the present study, CPT is modelled by static elastic-plastic small strain finite element method (FEM) analysis of axi-symmetric problem. Undrained soil properties and Tresca yield criterion is used for determining cone resistance of clay. Sand is modelled by using drained soil properties and Mohr-Coulomb yield criterion. Cone penetration problem is formulated as a collapse load problem. Associated and non-associated flow rules were used for modelling. A number of numerical experiments were performed to determine rational size of discrete region. Received dimensions of region were used for further research.
