Abstract: In a previous paper, interaction relations based on the lower bound theorem of plasticity were derived for moderately thick pipes subjected to biaxial shear and bending, axial force, twisting moments, and internal or ...

Abstract: General interaction relations for pipe sections subjected to combinations of normal forces, internal or external pressure, twisting moments, biaxial bending moments, and biaxial shearing forces are developed. The derivations ...

Abstract: A finite-element formulation that captures both the St. Venant and warping torsional effects of open sections is developed. The formulation is applicable to prismatic thin-walled open sections commonly used in steel ...

Abstract: Two finite-element formulations are developed for the general distortional analysis of beams with monosymmetric sections. In the first formulation, cubic and linear Hermitian polynomials are adopted to interpolate the nodal ...

Abstract: Conventional analysis methods for beams do not distinguish between transverse loads that are applied at the beam centroidal axis and those acting either above or below the centroidal axis. In contrast, this paper formulates ...

Abstract: A family of interaction expressions are developed for steel elliptical hollow sections (EHSs) subjected to combinations of axial force, biaxial bending moments, torsion, and bimoments. The formulation is based on kinematically ...

Abstract: Plastic interaction relationships for pipes subjected to biaxial bending, biaxial shear, torsion, axial force, and internal/external pressure were recently developed. This paper reports a full-scale experimental program ...

Abstract: The present study complements recent published work by developing a general closed-form solution for the analysis of steel beams reinforced with glass-fiber-reinforced plastic (GFRP) plates under general loading and boundary ...

Abstract: General interaction relationships for hollow structural square sections subjected to general combinations of normal force, twisting moments, biaxial bending moments, and biaxial shearing forces are developed. The lower ...
