    Using less than minimum prescribed fillet weld size

    the strength of the weld is in the leg size not the cross section, by reducing the size from requirement you are also lowering the safety factor of the engineering calculations. If it calls for a 1/4 welds, then a 1/4 it should be. master ICC inspector, AWS CWI

    moment welds.

    Had a meeting with the erector today, after looking at the steel, the fabricator was nice enough to slot the bolt holes about an extra 3/8 so they is some slack for adjustment. The steel erector today told me, he has done many of the bldgs, and he wasnt going to comply, he was just going to weld...

    weld plates, I beam bearing.

    So if the bearing gap is over a 16th, I could use the argument that it violates the wps on root opening. I know the weld is suppose to be stronger than the metal welded, but would you want the whole column be supported on the weld itself. OK I can understand when the total load is applied that...

    weld plates, I beam bearing.

    This is an issue I been fight with steel erectors for years. If the weld plate is not flat the beam wont set bearing on the plate. Some will have 100% on the weld and not the plate. This is the same with K joist. I like to see 100% bearing on beams and as much as possible with k joist. My...

    Extrapolation of Geotech Study Results

    I would say no, even if the material on top is the same, doesnt mean the material fifty feet down is. There could be a layer of muck, fat clay even a sand layer. water table could be different. master ICC inspector, AWS CWI

    structural question, cmu bldg, weld plates.

    I got a question on weld plates on a typical cmu bldg. How important is the bearing plane of the weld plate concerning the setting of red iron beams and k joist. Is this a critical variable. I been raising hell about the weld plate not being level, when the beam goes in, there a void under the...
