Loving the conversation. Thank you all for sharing our opinions, insights, and experiences. One clarification I want to make is that I was asking about 'toolboxes' of individual employees--not the companies 'toolbox'. Regardless, I think the conversation has touched on both. I will add to this...

Hi all, I'm curious how consulting business owners here feel about their employees using and building their own personal engineering toolbox. Everyone has their toolbox to help them do their job more efficiently and to a higher degree of quality, from Excel design spreadsheets to...

Motorcity--I don't have access to my calcs/drawings anymore and I can't recall unfortunately what I accounted for in deflection. The retaining wall is buttressed by jogs at the top of the stair, and it's a centered footing.

Hooked bars sticking out of the formwork with 2x knockouts for a shear key. Here's a close-up of one of the photos above.

I designed something similar a few years ago that was built within the last year. It wasn't 5 ft if I remember correctly, more like 4'. But they were 4" concrete cantilever treads. They were poured separately from the wall.

I would definitely check KootK's option 1. For shear design, you lose capacity due to the reduced depth, then a Cvr factor of 0.72, and then a (dn/d)^2 (reduced depth over gross depth)^2. If you're shear doesn't work with the notch and you're willing to rely on non-North American design...

In your case, vf should be 89 kN / 3 panels * 2 (approx 2:1 aspect ratio) = 59 kN, which is the avg of the two shears in your line model. Not sure why you're line model has that slightly different.

Amazing feedback! Thank you. I did not catch the influence vs tributary area differentiation in ASCE but now I understand.

Hi all, What are engineers out there doing for long span situations where a girder is eligible for a live load reduction (floor live load, trib area>400sf--ASCE 7), but the trib area for the connection at either end of the girder is <400sf (ie 700sf for the girder, 350 sf for the connection)...

Thanks robyeng. Not sure what happened to the attachment. The (now inserted) inline image is the attachment. So actually the even areas was the reason I started looking into it in the first place. I'm just starting to design with canadian rebar for the first time so it piqued my interest. I...

Hi all--just wondering if anyone knows how the sizes of canadian rebar became convention. The US has sizes that are in increments of 1/8" diameters, Europe has sizes that are in even # increments of diameters. Canada has size names that are in increments of 5mm diameters but the actual diameters...
