The design principle is that the welded connection shall have a capacity equal to atleast the moment capacity of the plate.Note that the bracket behaves as a cantilever so the point of maximum moment is the connection itself.Steel partial factor $= 1.15$ Permissible stress in steel $= \frac{275 \text{ N/mm}^2}{1.15} = 239 \text{ N/mm}^2$Welds in Shear,Bending,Torsion and Axial Loading User Feb 14,2010 2 Design of Welded Connections 2 1 Stresses#0183;equivalent stress represents a stress value in shear.In general,the design strength relevant to this case roughly equal to py/sqrt(3).For example,a value of 0.55 Us in BS5950-1:2000,which implicitly assumes that the weld stress is in shear.When designing fillet welds to BS5950,the design weld stresses happen to be:Welded joints - SlideSharewelded joints 1.prepared by jishnu v engineer bhel-isg 2.1) introduction 2) advantages disadvantages of welded connections 3) types of welding processes 4) types of welded joints 5) stresses stress concentration factors of welded joints 6) analysis of unsymmetrical welded sections which are axially loaded 7) special cases of fillet joints 8) solved examples

Lecture 11.2.2 Welded Connections - Basis for Weld Calculation In the elastic stage,which is of interest in fatigue design,the stresses are not uniformly distributed,especially not when the filler metal yield point is much higher than that of the parent metal.For example,consider a bar loaded by an axial tensile force as shown in Introduction to Welded Joints Introduction1.The load is distributed uniformly along the entire length of the weld,and 2.The stress is spread uniformly over its effective section.The following table shows the stresses for welded joints for joining ferrous metals with mild steel electrode under steady and fatigue or reversed load.Stress Concentration Factor for Welded JointsHow to Design Fillet Weld connection for Steel Trusses According to clause 4.5.3.1(1) of EN 1993-1-8,design resistance of a fillet weld should be determined using either the directional method or the simplified method.The directional method is based on the comparison between the design tensile strength and the applied stress in the most severely loaded part of the weld throat.
