    Distance between splices

    It is a mistake by the concrete contractor. He constructed the pedestal+anchor bolts with 100 mm offset by referring to old drawings. The steel contractor brought the steel columns with revised drawings.

    Distance between splices

    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...

    Weld between Web and flange shear flow Built up box

    Dear All Thanks. I have few more questions on this 1) it is a built up box of RHS 300x120x16x12 2) Do we need to consider Axial force in the member . If not why. Any references for the same 3) If there is torsion how to consider as a part of built up weld Regards M.S.Boobathi

    Weld between Web and flange shear flow Built up box

    Dear All 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...
