Dear All
Are there any specifications for the distance between splice. The contractor erected the column 100 mm outside with a stub.
He also brought the beam with its original length. Now asking for a splice of 100 mm length. Beam is HSS 500x400x tk. Usually, we will allow the splice Depth or...

I am designing the weld for Built up box RHS 300x120x16x12 ( subjected to Axial force +small flexure)
The shear capacity = 2*0.6*0.9*fy*t*D = 2*0.6*0.9*355*12*300 = 1380 kN
Equivalent horizontal shear =Vmax*1000 *AF/I = 1380*1000N*[120X16]*150/116009344 = 3426 kN
Required fillet weld...

As per AISC-360 bearing strength of bolt holes is given as
i) When deformation at the bolt hole at service load is a design consideration
Rn = 1.2lctFu ≤ 2.4dtFu .
What is the meaning of "service load is a design consideration "
and when to use Rn = 1.5lctFu ≤ 3.0dtFu
Thanks and regards...
