We're having a discussion among several very experienced engineers in our office and now we're more bewildered that it has taken us this long to realize we have multiple definitions for the same term: STORY DRIFT. We're in seismic country so we have code-required drift limits.
ASCE 7-16 section...
This has been a repeated question over and over on this forum. I've never seen an answer I felt "solid" about using though I've gotten some good advice on how to approach it. Today, I believe I have stumbled upon a "source" that can be used for these types of "through bolt" type problems in the...
I have a SDC C all-steel 3-story building. The building is an OMF building for the top two stories and OCBF building at the bottom story.
The owner wants to add a mezzanine between the foundation and the first level for part of the building plan (not full). He's very adamant against adding in...
I have a question on designing composite steel beams. RAM steel will give a minimum number of studs but I'm not sure how to make proper use of it.
For example, I'm designing a 30' long beam with deck perpendicular to the beam. The deck has rib spacing of 12" oc. But RAM tells me the number...
Does anyone have any source or a good methodology for the capacity of a threaded rod (or bolt) placed through a masonry wall with a washer or plate on each side?
I'd be interested in it for both grouted and ungrouted CMU (and with Appendix D creating issues in concrete the way it is, it seems...
Does anyone know of a quick reference for estimating weld time? Everything I'm finding involves calculations which I'm certainly able to do but it seems like to me there should be a table somewhere that says for a 1/4" fillet weld they can do an average of "X" inches per hour.
Problem is I...
I'm trying to check attachment of a steel stud to a masonry wall for uplift resistance at the end of a steel sheet shearwall.
Can anyone point me in the direction of how to find values for bolts (1/2" diameter) in shear through cold-formed steel?
I need some help in determining if certain welds require nondestructive testing. Typically, our project notes have always said "all complete joint penetration welds require nondestructive testing".
In my situation, it's been discovered it wasn't provided, but the welds are now well covered up...
I'm designing a concrete building in SDC D (IBC 2003). We wanted to use concrete shearwalls alone, but the SDC and height requirements are forcing us to use a dual system of shearwalls and special moment frames.
Does anyone know if it's possible to create frames that meet the "special moment...
I'm considering using some high strength masonry on a job. My initial calcs suggest an f'm of 4000 psi would be required.
What I can't seem to find is the required net strength of the CMU units to get me there. All the tables I've found only go up to f'm=3000 psi, but I've found plenty of...
