Looking through the NBCC I'm not seeing anything related to applying or accounting for any vertical acceleration due to seismic ground motion: just horizontal forces only. Am I missing something or is the 0.9DL combo considered to address that?
To any engineers familiar with the NBCC's seismic design: are there any provisions for including some portion of snow or ice loads as part of a structure's seismic mass? I looked through the NBCC and Alberta provincial codes and didn't see anything regarding this but I could be missing...
How does the Canadian NBC or engineering practice address the weight of glaze ice on structural components for vertical, wind, and seismic? The NBCC and Alberta Code I've got access to don't seem to even mention ice loading at all--which I find surprising given how much of Canada is so far...
We've been getting weird results when anchoring equipment to concrete with the application of Ω[sub]0[sub] at the lateral force E. We used to follow the code literally but after getting enough large equipment (over 25k) that no reasonable number of post-installed anchors would work for) and some...
I realize slab on grade point loading may be an old topic but has anyone noticed an order of magnitude discrepancy between Enercalc slab on grade capacity compared to the capacities given with the Ringo & Anderson formula?
Any opinion as to which is "more correct": the Enercalc formula, if I...
Our firm is working on a solar project in a "special wind region". We're not familiar with working in these regions and am wondering how/where the local municipalities post these design wind speeds. Most the towns we've tried to contact, and their respective websites, don't make this information...
Hi, I have an increasingly common issue I'm at an analytical loss on how to deal with. I'm trying to develop quick, ballpark vibration values for slabs on grade for equipment.
I work in Silicon Valley where there is a lot of extremely sensitive equipment being installed in labs. I'm...
