Architect wants to build a 60 ft. long by 20 ft. wide open plan (no interior walls)structure. The short direction roof will be broken up mid span with clerestory windows. It will be framed with custom timber scissor trusses. What's the best way to handle scissor truss thrusts and take the wind...
Architect wants to have 70ft. atrium columns using HSS sections forming a 4-sided ladder. I can figure the "r" of 4 HSS sections spread apart from each other. The question is, how to figure the spacing of the horizontal ladder pieces to make sure the overall column is not too slender. Ideas?
All,
I'm looking to get a better understanding of using CLT deck with gyp concrete topping, supported by steel beams and columns for a five story institutional building. Specifically, what to pay attention to when using the CLT as a floor diaphragm sending lateral forces to concrete shear...
Does anyone have any insight on proper methods to analyze and code check a 1970's era pre-engineered metal building (tapered columns, moment haunch, tapered beams, etc.)? The client wants to add 4 -6 new rooftop RTUs. Will likely need to load the PEMB purlins too. I'v attached a typical...
I have an historic free-standing brick wall (no roof but with returns) approx. 12' high with a serious out of plumb condition at the top. It needs to be shored for an extended time, and I don't have room for a conventional shoring brace on the compression side. Has anyone used debris...
I'm working up some design options for a client wanting to use heavy timber columns and beams for a series of one-bay frames parallel to each other for a greenhouse/conservatory. I have very limited options for braced frames or shear walls elsewhere, so these individual frames need to act as the...
I've had some success negotiating with architects, where they agree to do the final drawings with sketches, notes and schedules provided by me.
It has the advantage of eliminating the time suck of final drawing preparation, allowing me to concentrate on the engineering. I, of course, review and...
I'm looking for recommendations for an application that would make drawing section/detail sketches to scale on a tablet like device. Ideally it would be easy to use and learn and be able to bring in steel sections, rebar templates, etc. Does Sketchup offer a structural detail...
