Stress and Stiffness Analysis of Weld-Bonded Box-Section Beams Subjected to Bending Moment : The Case of Considering Shearing Force

Abstract

Stresses and stiffnesses of weld-bonded box section cantilever beams with a concentrated load at the free end have been studied analytically. The influences of spot-welded spaces, Young's modulus and thickness of the adhesives on the stress distributions and the bending rigidities were investigated considering the shearing forces of the beam. Maximum shear stresses in the adhesives occur at the inner edge of the adhesive layers and decrease with the decrease of Young's modulus and increase of thickness of the adhesives. The analytical results were consistent with the results obtained using the finite-element method.
