Hi all:
I'm a bit confused about the approach for flagpole foundation designs. I designed a pole foundation based on IBC's straightforward approach in Section 1807 (Unconstrained round piers subject to lateral load). It was relatively narrow and deep (~2.25' wide and ~7.5' deep.) The...
Afternoon, all:
I've got a question on a design process that I'm trying to put together for what feels like a simple situation, but my experience with foundations like this is limited. We're going to be surface-mounting an 8' chain-link fence on a continuous concrete curb, 12" wide. The curb...
Hey all, I've got a question about how ladders in an industrial setting are typically analyzed. In verifying a proposed stationary 16' ladder that uses 2-1/2"x3/8" flat bar for the stringers and 3/4" pipe for the rungs, I'm not entirely sure how these are generally modeled. My first instinct...
Hi, folks!
I'm looking for some literature to better understand the mechanics and design of circular tanks under net external pressure (i.e. an empty or partially empty tank that is fully or partially submerged.) Presumably it will be a stiffened steel shell. I'm unsure of the extent to which...
Good afternoon, all:
I had a question regarding the way ACI-318 handles shear friction. My understanding of the concept is that at, say, a retaining wall's base which was poured separately from its footer/slab, shear resistance is provided by the compressive component of the moment couple...
Hello, all:
I had a question about restraining flexural members against lateral-torsional buckling. I suspect that there's some misunderstanding on my end about beam theory that I'm not properly thinking through. When beams in frames are braced laterally to beams in an adjacent parallel...
Hello all:
I had a question about how to properly reinforce the corner of a thin-walled rectangular open-topped tank. The tank walls are pretty short (<4'), so a 6" wall looks to be sufficient for strength. At the corners, where the horizontal moments are largest, though, I'm not sure how to...
