When specifying anchor bolts to attach steel columns to concrete, everything I read suggests specifying ASTM F1554. I have specified Gr36 and my supplier says that it is much easier and cheaper to get ASTM A193 B7 bolts. Those I read are not as ductile and are stronger. What would preclude me...
The pre-2010 ASCE 7 used a minimum wind pressures of 10psf on the vertical projection of the entire building and then in 2010 and thereafter the minimum pressures are 16psf on walls and 8psf on the roof. This thread is not about ASD vs LRFD, I found posts on that, this question is about the...
I use the VA software for frame analysis and I get along pretty good. When it comes to modeling plates I struggle a bit. I'm curious if there are any users out there that would be willing and open to having dialogue and answering questions off-line and ideally be able to learn from each other...
To expand upon the subject line, does a note like "I have designed this project according to ASCE 7-10 specifications?" immediately above or below my signed seal limit my liability as to what I am "certifying" by stamping those plans? Does anybody use clarifying notes to limit exposure when...
I am wanting to get some test equipment to do some small-scale testing for various structural connections and assemblies that I've dreamed up. I am not wanting to become a certified testing laboratory, but I'd like to get my hands on some decent equipment. I'm basically looking for a data...
Not sure if this is the right venue to ask this question, but my exposure to other designs, methodologies, is quite limited and so I'm looking at this broad group to answer a simple question. If using datums to denote elevations of finish floor and framing do you call out finish floor as...
On a bulk storage fertilizer containment building with 16' tall concrete walls I'd like to brace the tops of the concrete walls to not have to design pure cantilevered walls. The material will actually be stored HIGHER than the walls so a brace at 16' would be embedded in the stored material...
I'm really struggling with this topic. I'm utilizing the Simpson Strong Tie Anchor Designer Software and I'm having a real hard time getting any anchors to work. Maybe what I'm trying to do is as impossible as the program is making it seem. I'd appreciate some help with this.
What I have:
I...
I'm making a light-gage steel truss out of stud shapes. I'm getting that I need to brace both the top and bottom flange of my compression chords. My top chord top flange of course is braced by my roof decking and I don't have a ceiling to brace the bottom flange of my bottom chord. Is this...
