Have an existing X-Shape lifting device that I have been asked to determine a rated capacity. The device appears to be of the type where someone in a shop through some shapes together and used it to lift something in the past without ever being engineered. I say that because of how the device...
Analyzing this existing rectangular slab for some additional loading. The slab was designed in the mid '50s and I don't quiet understand the details. It appears to be a one-way slab, with two reinforced monolithic beams spanning top to bottom within the 20' x 20' grid. With one side being 20'...
Have an existing, elevated 9" thick concrete slab with several penetrations through it that have been requested to be filled to eliminate tripping hazards. Each penetration is void and has a grout ring and steel cover plate installed over them (see attached picture). It appears each penetration...
All,
I have a conceptual question regarding calculating the support reactions for a multi-bay frame supporting an out-of-plane load. Please see the attached sketch. All the literature I could find deals with loads in the same plane as the frame.
Without modeling, I am looking for a way to...
All,
I am reviewing a foundation drawing for a vertical vessel that was designed by the M.W. Kellogg company in 1965. I need to evaluate the anchor bolts for an additional loading scenario. The original drawing I found only list an anchor bolt code (Size 22, Type CU, P 30) for the anchor bolts...
I have a continuous W12x53 steel beam that spans 50' over four supports. The steel beam will have a steel C12x20.7 channel placed on top of it to create a "track" to move a load out of a building. See the attached sketch.
I have sized the beam to handle the entire load without considering the...
I'm designing an industrial, one-story building slab that will require plumbing and electrical conduit placed within the slab. Is there any general guidance on how to embed commodities within a slab? I assume ACI has some restrictions on conduit size and location within the slab. I've never...
I have a three bay, rigid, plane frame that I am analyzing for a rolling 50 kip vertical load. The frame has pin connections at the base. I am trying to figure out how to analyze the three bay frame by hand, but have found very little technical literature on analyzing multi-bay frames other than...
