Hi folks - I am working on a warehouse type building that consists of a steel frame with insulated precast concrete bearing walls around the perimeter. The architect has laid out the structural grid, and every single grid line aligns with a precast panel bearing joint. I have used insulated...
Old Dawg this is exactly what I was looking for, and is much more in line with what I'm used to using. Pulling up and reading ACI 360, I believe that the 1/2" x 3" rods they are currently using are likely doing very little, and that aggregate interlock is more likely what is keeping these...
Hi folks,
I recently came to work for a well-established construction company, and their typical detail is 1/2" x 3" slick rods at 12" on center for use in construction (cold) joints in industrial slabs. I have never seen dowels this small (diameter or length) used for load transfer (my...
It is not a new building - it is a 100 year old building with a 15 year old slab on grade that was destroyed by current lessee's use (hypothetically). The slab is not turned down in any area; isolated from all foundation walls and isolated footings. While I've argued ad nauseum that the slab...
This is deep in some technical weeds, but a client asked me to define the floating slab on grade in a two-story building as either a "flooring" or a "foundation" (this matters due to some leasing agreements). I can see two arguments - (1) the primary building structure loads are transmitted...
Thanks - I should have just gone straight to good ol' AISC. It's got pretty good guidance on negative flexural strength for composite flexural members in chapter I. I think I had been warned off of doing this by a senior engineer long ago and had just taken it as gospel without researching.
I am being asked to bid on doing the connection design for a small steel-framed addition to an existing building. In reviewing the drawings, the engineer of record has concrete slab on composite metal deck, with composite steel beams and the associated shear studs called out on the framing...
