## Lap fillet weld bending

I have to design a lap fillet weld joining a plate to the top flange of an beam. There will be a force acting down on the plate so the weld will be bending. How do I calculate the stress on the weld?

l l <- Forces acting on the plate and beam
----------------- The plate is the length of the beam

 Recognitions: Gold Member Homework Help Science Advisor For cover plate weld design, you have to calculate the longitudinal shear at the intersection of the cover plate and top flange of the beam. Does tau=VQ/It sound familiar?
 I haven't used that equation before, so I have a few questions: Is t = thickness of the flange or the breadth of the flange? Or, is it the thickness of the flange or the breadth of the plate? When I have calculated tau, where do I go after that? Force per inch of weld direct vertical shear = f = P/A? Then,calculate Force per inch of weld due to bending too? Add them, and divide by allowable force per inch of leg? tau = shear load / (throat thickness)(length) to calculate t? Thanks
