long story short. The fabricator messed up and installed bolted moment connection plates that are too thin. What methods are available to reinforce the plates and welded connections to the column?
Does anyone else have past experience seeking a waiver or exemption from a building official related to rooftop live load requirements for assembly space?
I have a client seeking to reinforce an existing roof and hoping to design the roof reinforcement for a lesser
load than the new DL +...
Has anyone else utilized more than one hairpin to resist large thrust loading? Most examples use one hairpin and this is fine for smaller buildings, but if the thrust is very high can two or three hairpins per column be utilized?
Tie rods cannot be used for this scenario.
I know when designing wood panel shear walls it’s common to utilize the floor framing DL and self weight of wall to counteract overturning, at least a portion of that load is used.
Is using the DL common practice for Flat Strap shear walls in metal stud building as well? Most of the software...
I’m looking for resources like books or webinars on arched concrete roof design. I’d like learn more about them for a potential project and research any software programs capable of designing arches.
Any help is appreciated.
I’m looking for a good resource book with details or some examples of FMC connection design.
These would be for connections to column flanges and webs. I know how to design these connections, but I'm being tasked with something specific. The fabricator would like to re-evaluate specified FMC...
I hope someone can help me fully understand the requirements of ACI Appendix D.
I'm having difficulty determining if I should be analyzing my cast-in-place bolts for the baseplate using a "cracked" section analysis, which would apply the reductions to meet the requirements of Appendix D. My...
I've been tasked with providing design for support of wall and ceiling plating for an MRI project.
My question is regarding magnetic pull. I know the dead loads I need to design my structural elements for, but was wondering what, or how much extra load I should be considering to account for...
I have to analyze an existing waffle slab and have been looking for the correct procedure to convert my slab and ribs to an equivalent average thickness. CRSI shows a charts, but I need to do a handcalc. The formula CRSI provides has a "tr" variable, which is the equivalent thickness of the...
I am currently talking with two fellow employees about possibly starting our structural consulting firm.
I am young and currently sitting for the SE exam, while the two other guys are a little older and are PE's in the states we would work in.
Most likely, ownership of the firm would be...
I have a fairly simple question. Most of the CFMF jobs I've done in the past have exteior CF studs and we usually specify on the drawings stud depth, gauge, and detail general ways of connections the studs to the superstructure. We spec we develop is a performance type spec, which requires the...
