I agree with CANPRO as well, as far as the sketch is drawn. However, if I'm understanding the description correctly, this is basically a retaining wall, yes? If so, you wouldn't have a constant 1kN/m2 load over the whole face, you'd have a linearly varying pressure from 0kN/m2 at the top to X...

Thanks dhengr! Don't really have time to sketch this out and attach it, but I think you got the gist of what I was trying to say. :) And I finally talked some sense into my coworker, he agreed that flexure would not control for these lifting pins (and certainly not to the extend of PL/4); he...

I'm evaluating a number of existing lift beams located at a dam using ASME BTH-1 for below-the-hook lifting devices. In checking my calculations, my coworker told me I should be checking the flexure of some of these lifting pins that are inserted into the gantry crane lifting hook eyes. I had...

I'm checking the design on a cantilevered retaining wall with equal quantities of steel at equal distances from each face (e.g. #6 bars at 12" o.c., centered 3.5" from each wall face). In looking through the analysis equations, since the steel areas are equal, a couple of quantities drop to...

My understanding is that horizontal reinforcement is primarily used to control shrinkage and temperature cracking.

I'm just curious how one goes about designing a reinforced concrete shear key. It wasn't anything I ever heard about in school and none of my textbooks even mention it. What are some good resources? More specifically, my problem basically deals with a rectangular concrete channel in the...
