    Champlain Towers Collapse

    I realize that this issue has been discussed at length and there are many threads on the subject. I skimmed some of the threads but did not read all of them. Has there been a discussion of what is the liability of the SE is in the case? “We had no idea the building was in imminent danger,”...

    Drawing Revisions by Project or by Sheet

    Thank you all for your comments. I think maybe I am changing my mind. Especially for the smaller projects. Several things are making me re-think my position: Most people are looking at drawings on tablets or screens now. So re-issuing a complete set makes sense so that the latest complete set...

    Drawing Revisions by Project or by Sheet

    I have been reading some older posts on here. I wanted to see what the new consensus is. I am old school and I guess my way of tracking revisions is by sheet. As it is explained to me: By sheet means that only the sheet that is revised gets a raised rev level. Some guys in the office don't...

    Does anyone have a BOCA 99?

    I am trying to reverse engineer A tank foundation (mat on drilled piers) I have a soils report that states Av=0.14 and Aa=0.13. I am trying to determine the base shear that was used for the original design.

    NDT on a column Splice

    SandwichEngine, thank you for the information. I do not have a copy of D1.8, but will order one. Does the shop have to be "AISC Certified"? Or what constitutes an Approved Fabricator?

    NDT on a column Splice

    I am splicing 2'-0" onto the bottom of a 20' tall HSS 12x12x5/8 column. Bottom is idealized pin and top is a moment connection. Our plan is to use a CJP weld to splice the column. Application is moderate seismic. Is any NDT required on the weld? Ive been reading AISC and AWS, and i can't...

    Bolt Prying

    There is also a newer version of this book but the table of contents is different. Do you know if the same procedure is covered in the newer version? Maybe I have to buy them both! :)

    Bolt Prying

    Thank you all for the comments. I will purchase a copy of this book. Not that I need an excuse to buy more books!

    Bolt Prying

    What are your thoughts on adding another gusset in the beam web on the other sides of the bolts? Does that eliminate the prying force in the flange and the bolts?

    Bolt Prying

    I think the original sketch I posted was too small to see what is going on.

    Bolt Prying

    Yes, I understand it does not change the load or the bending stress in the beam. I will check web crippling, yielding, etc. The loads on the connection require a 1 1/8" beam flange to resist the prying. If I include the prying force in the bolt design, the 1 1/4" bolts are overloaded by a...

    Bolt Prying

    I don't think a thicker cap plate resolves the issue for the thin beam flange. I think that gussets on either side of the bolts or welding a doubler plate to the underside of the flange may resolve the prying force, but I can't find a reference that confirms that.

    Bolt Prying

    I am evaluating this connection and it has significant prying. The detail shows thick washers on the top side of the flange. based on my understanding of prying, I don't see how this eliminates prying. If it does, how do you determine the thickness? Does anyone have any experience with using...

    Light Gage framing roof truss connection

    Has anyone used a side-lap connection for a roof truss to a wall stud? Truss span is 40 feet. I have a building that is CFS bearing walls. The ones I have done in the past had regular gable roof trusses. So we just set the trusses at 24" OC on top of the wall. We placed an extra stud under...

    Plain Concrete Design

    So if I am using the h-2" for the thickness, I assume I need to utilize h-2" to determine bo as well.
