RESUMO

This work presents theoretical and implementation procedures related to a proposal for the design of welded joints, based on finite element solutions for plate models. The technique consists on obtaining the required dimensions at the throat section of the weld, required to resist prescribed loads, based on stress component evaluations nearby the weld, along its length. In the calculations some simplifications on the stress component distributions along the plate thickness are considered, typical of thin walled plates. Evaluations of the proposed methodology are performed considering the weld design of plates under standard prescribed - transverse shear, membrane and bending loads - where the numerical results are verified against analytic results. Solutions for the design of plate welds in complex structures are also presented and discussed
