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: The present study develops a finite element (FE) formulation based on the kinematics of thin-walled beam theory to determine the elastic lateral torsional buckling capacity of singly symmetric beams strengthened with cover ...

Abstract: The objective of the research was to assess the structural capacity of reclaimed asphalt pavement (RAP) as a base layer and to investigate the effect of RAP content, moisture content (MC), freeze-thaw (F-T) conditioning, ...

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: The best-value (BV) procurement process uses other key factors as well as bid price in the evaluation and selection of the best-performing contractor for the job. Contract time, lane rental, warranty, and quality of delivered ...

Abstract: Modal properties of light roofs such as cable roofs backed by cavities with openings are theoretically investigated. Taken into account are the interaction between the roof and the air enclosed by the cavity, the air outside ...
