Sažetak
This paper presents a shear deformable numerical model for the large displacement analysis of beam type structures. Shear deformation effects are accounted for the composite cross-section considering bending-torsional coupling effects. Cross section characteristics are calculated based on the reference modulus, with ability to model different material configurations. A numerical algorithm for calculating the geometric characteristics of a composite cross-section is developed. Various material configurations are considered. This procedure is incorporated in the 1D beam model for the nonlinear stability analysis, previously developed by the authors. Large rotations are allowed, but small strains are assumed to occur. Several benchmark examples are demonstrated for verification purposes.
