Find the size of E70 fillet weld required for the shear and tension connection shown. Use the following details:
P = 250 kNe = 130 mmb = 150 mmd = 200 mmAssume the column and bracket plate does not control the strength.
A hanger is suspended from a plate that is welded to a wide flange beam as shown. The plate requires a 1”x1” chamfer in the inside corners to clear the fillet radius of the beam. A ¼ inch double sided fillet weld is used with no welds placed at 1”x1” from the inside corners as shown in the weld configuration. Determine the maximum load the hanger can carry using ASD and the Elastic method if the eccentricityof the load from beam centerline is 7”.
Determine the adequacy of the hanger connection in Figure Account for prying action.
a. Use LRFD.
b. Use ASD.
