For common knife‑edge simple beam shear connection as shown in the figure below, it appears that the shear resistance can be improved by welding across the top edge of the angles. However, beam shear connections must exhibit sufficient end rotation to allow the attainment of bending capacity of a simply supported beam, for example. Therefore, welding [...]
The minimum size of a fillet weld as measured should comply with Table 4.4 of CSA W59-13, unless a larger size is required to provide the calculated weld resistance. The long-standing code provision for minimum fillet size aims to reduce the cooling rate. The presence of hydrogen and fast cooling are major contributing factors for cold [...]
The effect due to shear lag in a tension member is usually accounted for by means of an effective area method. For weld-connected members, Clause 12.3.3.3 of CSA S16-14 applies to members of various cross sections in general. When only one leg of an angle tension member is attached to its end supports, with longitudinal fillet [...]
Here is an example on how to apply the strength reduction factor, Mw for multi-orientation fillet welds. In the weld configuration shown in Figure 1, 8-millimetre fillet welds are used, Xu = 490 MPa and the plate is G40.21 350W steel. Note that the farside plate is thicker. In accordance with CSA S16-14 Clause 13.13.2.2: Vr = [...]
