Fillet weld design – two methods steelconn

Jan 21 Eurocode gives a designer a choice between two methods for the design of fillet welds the simplified and the directional methods There is no specific guidance on which method to use and in practice the choice is usually made on practical grounds In the directional method the force acting on the fillet weld is resolved into components parallel and transverse to the plane of
