I am checking the capacity of an existing parking garage, originally designed for passenger cars (live load of 50 psf was used) to use it for parking vans and light trucks. The vans are around 9,000 lbs and are parked on one floor. The trucks are 19,000 lbs and are parked on a different floor...
Hokie, should all the hanging stirrups be surrounding the headed studs or close to them? It seems that the legs of the stirrups on the other side of the beam (away from the embed) wouldn't be very effective.
In the attached british standard for design of headed anchors in concrete (which we the US guys don't use) they talk about the concrete "cone" failure as being one of the modes of failure. (concrete cone failure doesn't happen in the typical corbel unless you are using anchors). The document...
Thanks hokie66. When you say hanging to the top of the beam it seems to me looking at the breakout cone in the sketch that there is not much of the beam left at the top to hang from. We would be taking the 150 kips with that small section of concrete left at the top. It doesn't seem possible. Am...
Thanks. I am attaching a quick sketch of the detailhttp://files.engineering.com/getfile.aspx?folder=f5ac31fe-1a70-4dfc-815f-f5004493c6d1&file=photo.JPG
Thanks Jed. If concrete breakout doesn't work Appendix D allows you to take the force with rebar. This is easy if you are at the edge of a wall or a slab. But can you do this in a beam? Could you use shear friction of the longitudinal reinforcement? any other way? If this works somehow I don't...
I have the usual references for design of embed plates in concrete walls, concrete slabs but how do you design an embed with headed studs into a concrete beam. The embed is used to conect a steel beam with a very large reaction (concrete breakout won't work). The plate is as deep as the concrete...
