Hi y'all
New EIT here. I'm working on my first open canopy structure which I am trying to analyze based on the Ontario Building Code (based on NBCC). It's just a 5m x 5m (16' x 16') cantilevered umbrella and I'm designing the footing.
I have worked on a project with an overhang before and I...
Hi y'all,
I am designing some residential footings and the Canadian code isn't abundantly clear as to whether the crack control parameter is necessary for footing design. I have some pad footings whose reinforcement will be universally governed by satisfying z if that is the case.
I was under...
Hi,
I have designed a Can-am P-3615 composite slab for a project save for the specification of the wire mesh. I used the can-am techical guide for my design, but it states at the end that the design engineer is responsible for specifying the welded wire fabric.
I can't find anything...
Hi everyone,
I have been doing a lot of reading from prominent 20th century engineers (Eduardo Torroja, Nervi, Waclaw Zalewski etc.) and I am interested in learning more about stress trajectories and how to find them in different structural shapes. It is a really cool concept though it is...
Hi All,
I'm designing my first entry canopy as an EIT and I'm a bit confused how an entrance canopy would be analyzed for wind according to the OBC or NBCC.
The canopy projects about 15 feet from the facade of the residence (to which it is attached at the level of the second floor) and is 24...
Hi everyone,
I am designing some beams for a porch and I decided to throw a couple whose loading was more complex in a 2D plane in RISA 3D. I noticed that the required member sizes were smaller than I had anticipated, and when I looked at the detail report it showed the Mf to be about 75% of...
Hi y'all,
I'm working with the Canadian Wood Code O86 and I can't for the life of me find any mention of biaxial bending.
Am I able to analyze the combined effect similarly to how I would in steel i.e. Mfx/Mrx + Mfy/Mry < 1.0? I forget what this kind of equation is called but it's very...
Hi Everyone,
New EIT here and I am looking to get more adept at cantilever retaining wall designs as these pop up from time to time in my small office. I have a handle on the stability checks for the wall as a whole, sliding and overturning, but I am not as well-versed in the reinforcement...
Hi everyone -- new (3-months) EIT here.
I am working on my first detail where I will be specifying a modification to a beam profile to meet an architectural requirement.
My main roof beam has a large span ~50' so will be fairly deep (not yet analyzed but W24 section perhaps). One end extends...
Hi, fresh EIT here. I'm working on a few projects with complicated intersecting roofs and building volumes with exterior decks/roof decks and I am slightly confused about how in-depth the snow load analysis is needed for buildings which meet Part 9 in the code.
OBC 9.4.2 indicates the minimum...
