I need to calculate seismic reactions for some silos and bins that will be used to store grain. Can anyone recommend a good book or other resource for this. I may also be interested in some software specifically for bins and silos. Does anyone know of any?
In my state engineering graduates can now take the PE exam any time after graduation, and they aren't required to have 4 years experience. After passing the exam and gaining 4 years experience they can become licensed. So the PE exam is no longer an experience based test. I have been told that...
We have a client who is going to start working in Indiana, and we would like to work with him. Does Indiana require a firm to have a C of A? I can't find anything on their website. The person that I spoke with at the board doesn't know what I'm talking about, and referred me to the Sec. of...
I am designing an outrigger that will frame into an ICF wall. I will need to design a reinforced vertical strip of the wall to resist the moment induced by the outrigger. I think that I recall that the width of the strip should not exceed 3X the wall thickness, but I can't seem to locate that...
I have some really messy slab on grade projects coming up. Lots of heavy line and point loads with the slab changing thickness. I am considering trying spMats. Has anyone else used this software? I have FEA programs, but I am hoping to find a better alterative. Thanks.
I am working on a PEMB that will be in a very harsh chemical environment. We are considering galvanizing, but we would like to consider some other options. Does anyone know of any other coating that might hold up to this type of environment. I'm concerned about the primary members, but I think...
I am looking at a single girder bridge crane. The hoist runs along the bottom flange of a W section. When considering lateral load I have always assumed that the load is resisted by the bottom flange only. So I use Iy/2 for deflection and Sy/2 for stress. Is this too conservative? Does anyone...
Any suggestions on wood shearwall software? I don't care for Woodworks. I like the Daniel Li spreadsheets, but his software seemed to lock me out and I can't get it fixed. Any suggestions? How about Enercalc?
I am designing a three story multi-family structure. The floor framing consists of wood trusses. I am using a rim board to transfer
the shear to the floor below. Is this too conservative? Can I use the sheating to transfer the shear and omit the rim board...
I am designing a wood framed building with a monoslope roof. The heel height of the
truss at the high side is about 48". In the past I have used shear frames between trusses
to transfer the shear down to the top plate and into the shearwall. How do others handle this?
The trusses are spaced...
We need one new engineer and two drafters. We have been placing adds for several weeks
and have not heard from any qualified applicants. Has anyone else had this problem?
How are you dealing with it?
We are beginning design on a large warehouse structure. Tilt up walls with metal deck over bar joist roof. I have the Vulcraf tech guide 65 on expansion joints. Is this the best resource? What are some of you folks using for spacing between expansion joints?
It is my understanding that a PE can seal drawings for structures in WA with the exception of "significant structures" as defined by the Board. For example cladding design (curtain wall and panels), and small structures in Risk Cat I & II. Is this correct?
