Hey Everyone - I've got a question relating to the requirements outlined in section D3.3.4.3 in ACI 318-11 (unsure of the section in chapter 17 of 318-14). I'm currently designing embeds with H.A.S. at a podium with 13 levels of a proprietary structural system on top of it comprised of a...
Hello - I've got a question that popped up during shop drawing review of mild reinforcing of an elevated garage slab (w/ PT). To protect the reinforcing bar in the garage, the design team has agreed to epoxy coat all the mild reinforcing located at the top of slab. As a construction practice...
Hi All,
I'm currently working on a 19 story core wall building with 2 levels of below grade parking. I've been researching the backstay effect for some time now and am trying to capture its effects in design. I'm using ETABS as my structural modeling program. In order to design for the shear...
Hi All,
I have a simple question that I'd like to get some opinions on. My firm is designing some heavy moment connections for industrial pipe racks that use end plates bolted to column flanges. The connection from the end plate to beam is typically a 5/16" max fillet weld. We have some...
Hey all,
