Is there any guidance on assumptions for boundary conditions in reinf. concrete (articles, text books, etc.)?
I'd assume most, if not all end connections for concrete are fixed. Now when I say that, I'm not taking things down to the thousands or ten-thousands, but generally speaking if the...
In the prying equations the steel manual uses Fu, instead of Fy. On p. 9-10 there is a brief discussion that the design basis was changed to Fu "which provides better correlation with available test data".
I've found some other guidance online for some explanation in what is actually happening...
In ACI 318-14, Section 17.4.1.2 and 17.5.1.2, it says "futa shall not be taken greater than the smaller of 1.9*fya and 125ksi".
I interpret this as IF your ultimate strength of steel anchor is greater than 1.9*fya and 125ksi, then you use the smaller of 1.9*fya and 125ksi. Is that correct, or...
To my understanding a Complete Joint Penetration (CJP) would imply to backgouge the weld joint, but after several discussions with coworkers, etc. I'm starting to wonder if that's the case. If the weld is supposed to be a full-penetration weld, what constitutes "full-penetration"? Does that...
Recently I was doing some weld calc's using Spec section J, and discovered the Table J2.5 lists "tension" as a possibility for PJP weld joints. This made me scratch my head, bc it doesn't list tension as a check for CJP welds (bc CJP welds are governed by the base material) and that made sense...
Good evening,
I'm new to bridge design and have begun my first calcs for "somewhat" doing a load rating for some bridge repairs. My short career thus far has been just over 3 yrs in steel design, but primarily doing stress analysis for various structures (in a shipyard), and so I wasn't using...
