Hi all,
I'm having a frustrating problem that I would think has an easy answer. I'm designing a wall footing for bearing pressure right now, and can only increase the footing dimension in one direction. Imagine my surprise when my calculations say adding a foot in one direction of a footing...
Hi all,
I am having trouble figuring out how to get started on finding the wind loads (from ASCE 7-10) for a metal building open on 2 sides. The configuration looks something like the picture from Google that I've attached. The diagonal cases seem particularly weird, and I wasn't sure how to...
Hi all,
In ACI 3018 11.5.5.1, there's a minimum spacing stipulation of d/2 for perpendicular stirrups. This usually has not been a problem for me, but on my current project, I have a little cantilevered sidewalk on h=12" t-beams, making my d value only about 9". Stirrups spaced at 4.5" seems a...
Hi all,
So I have a bunch of multileaders (50) which have a text style that uses simplex font. However, they have all been overwritten in the "in place mtext editor" to arial font. I'm determined to find a way to change them back to simplex all at once, but can't find anything. If this isn't...
Hi all,
I feel sure this is an easy question, but I can't seem to find an answer in ACI 318 or my concrete textbook. But when calculating applied pressure to the soil through a rectangular footing, I'm sure you cant count on your whole footing area to bear evenly if it's 2'x10' for example. In...
Hi all,
I was designing an open pavilion structure (monoslope roof) for uplift using ASCE 7 Fig 27.4-4, only to find it has been decided that the building will have wall panels on the sides and back. To me this just looks like a parachute for wind, and the uplift and overturning forces should...
Lately at work, I have found drafting to be a bit tedious, which is no big deal. But as I have enjoying learning to automate things (like learning excel macros), I was wondering if anyone has any experience in using autocad scripts and macros for structural drafting. I was curious if this might...
Hi all,
I'm working on a pretty simple bridge substructure, but am required to use the ASD provisions in AASTHO 17th Ed (2002). I'm not very familiar with this, as my previous experience and education focused on LRFD. With regards to the concrete design, I see that design for some limit states...
Hi All,
I am a recent MS (non-thesis) graduate in civil/structural engineering. My masters classes were very structurally specialized and that is where my interests lie. I am currently working as an EIT at a smaller firm, but will likely have to move in 4 yrs when my spouse completes her...
Hi,
I'm a new engineer designing some open pavilion structures. Does anyone know any good ways to create your lateral force resisting system in these buildings? One of the structures has steel columns, so I designed those as fixed base columns, using AISC DG 1 for eccentrically loaded base...
