This may be a dumb question, but I'm wondering how you would design a concrete cantilever retaining wall (i.e. size the steel and the width). The wall is 12' high and about 25' long. Do I just take 1 foot sections and model them like beam-columns? Thanks in advance.
We've got an existing residence (one-story) with a pier and grade beam foundation. The existing piers are shallow. The house was built on fill and is sliding a bit so we are going to use drilled piers adjacent to the exterior grade beams that will extend down into bedrock. I'm looking for...
I am trying to analyze an existing carport that uses CEE sections (8" x 2-1/4", 14 gauge) as columns and a beam of a frame. The height is about 8' and the frame width is 10'. The columns are embedded in concrete. The beam is connected to the side of the columns with screws (no moment is...
I'm doing an analysis of an existing free-standing carport structure. The designer used 2-8"x2 1/4"x 14GA. CEE's as columns supporting a shallow slope roof. The wind uplift load will be very large and I'm concerned that the way he attached the columns won't provide enough strength. He...
I'm trying to size the steel for a concrete soldier pile and was wondering how I model the beam when determining the point of zero shear. I modeled it as a cantilever beam, with the very end of the pile embedded in bedrock considered fixed. Then I found the point of zero shear by summing the...
Hi,
I'm having trouble figuring out how to develop the moment and shear diagrams for this beam configuration I am working on. I have a continuous GluLam beam over 3 unequal spans. The two outer spans are 9' long and the middle span is 24.5' long. There is a uniformly distributed dead and live...
Hi,
I'm trying to design the column base plate for a residential moment frame. The foundation is an 8" by 29" grade beam with 3-#5's top and bottom on piers. The column is subjected to a 13 kip axial force and a 17 kip moment which seems to have a pretty high eccentricity of 15 inches (this is...
