Abstract
In this paper a nonlinear sectional formulation to account for full 3D stress–strain states on frame elements is presented, by means of a special cross-section model which allows for warping and section’s shape distortion. This formulation allows using a 3D constitutive model for concrete. Subsequently, the approach is applied it to the nonlinear coupled behaviour of RC sections under multiaxial internal forces considering inclined cracking pattern and failure stages. The applicability of th...
