I am currently designing a horizontal lifeline (HLL). Engineering Journal (2nd quarter, 2016) recently presented a paper by Thomas S. Dranger called "Design of Horizontal Life Lines in Personal Fall Arrest Systems". I'm comparing my previous HLL designs with this paper and am looking to...
sorry for the silly question, but i was wondering if there was a standard way to designate composite steel beams with multiple rows of shear studs. right now i have something like: W18x40 (2@15) [c=1"]. it's the "2@15" that i'm wondering about. i don't assume it's a huge deal, but if there...
i'm working on a portion of an existing concrete building from 1962. i have access to the original drawings. a concrete beam reinforcing schedule has columns for: top bars, bottom bars, bent bars, stirrup marks, and ties.
we're adding some load to a specific concrete beam. the beam is...
does the horizontal face/skin reinforcing of a concrete deep beam need to be hooked into the column supports for development? thanks for any help/thoughts; let me know if you need more information.
Sorry for the simple question, but you need a break every once in a while... Equation 18-3 of the 2006 IBC is:
d^2=4.25*(Mg/(S3*b))
Is S3 evaluated at a trial depth "d", so that it's an iterative solution? I'm just making sure. Thanks in advance for the reassurance.
I am evaluating an aluminum truss canopy that was built based on the 1997 UBC. I know member sizes and aluminum grade, but am having trouble evaluating the allowable compressive stress. The aluminum is 6063-T5, and I was using the welded aluminum properties. I'm using Table 20-I-C and...
