Abstract
This paper proposes a new method to calculate the wind-induced dynamic stress response of guyed mast earplate node, which considering the welding residual stresses in earplate weld joint. Firstly, a numerical simulation of weld residual stress of key nodes based on finite element method is presented. Then, taking the welding residual stresses as initial stress, the dynamic stress analysis of the guyed mast earplate’s weld was completed. The results show that in the dual role of the welding residual stress and the wind load, the von Mises equivalent stress of some hot spots in welds have exceeded the material yield stress of steel.
