Everybody,
Greetings. I'm looking for direction or a clue as to how I could find the prevailing compressive strength, f'm, of CMU during the 1940's and 1950's ... I'm greatfull for any help that can be given.
Thanks,
Scott

When an unreinforced masonry wall goes from no grouting to partial grouting, the compressive stress from any axial load (live or dead), should go down, as An increases correct?
In lieu of this, if I want to maximize my vertical compressive stress to offset tensile stress from flexure in the...
Hello everybody,
I'm working on a job were I used a baseplate with leveling bolts and grout for a column in biaxial bending. My question is that the client now wants to go without using the grout. Is it possible to model this situation in RAM, or does anyone know of a good resouce for sizing...
Hello everybody,
I have a wide flange beam end bearing atop a HSS column. The connection is transfering a moment, and has been checked for several of the criteria in section J10 and K. There isn't a need for stiffeners for strength purposes, but I read the code in section J10.7 to say that I...
The circled connection on this HSS and the other connections in general --
I feel like these should just be everyday fillet welds, but I'm not sure and I was hoping for a second opinion, would a flare bevel be proper to use for the joist to tube weld, (I know I'm showing fillet). Also are...
Hello,
I'm designing a pretty straight forward connection, a HSS 6x3 with a gusset plate (welded longitudinaly, (sp)). I'll have double angles bolted to the gusset.
Reference AISC 13th, commentary, section J, page 16.1-366-368 -- My question, is a vertical brace w/ single plate gusset...
Good Afternoon,
I recently had to do a large truss analysis / rehab project for a local factory. There were approx. 20 carrying trusses, all spanning 60' and approx 15 Jack trusses spanning 80'. After I determined the amount of additional steel that a particular member would need, I'd...
Hey all!
I have a project manager at my office that insists that the green book is a better asd publication than the newer combined steel code.
My questions are:
1.) If we're required to use the most recent version of a particular code, wouldn't the black book govern?
2.) If we're not bound...
Hello everyone!
I'm an entry level structural engineer, working on my first few tasks. Everything has been going great and I'm learning alot. Here is a lingering question that I feel was never really explained to me in school, and I can't seem to find an answer, or maybe I'm just not...
This my sound like a basic type question...
But is MWFRS included as C&C ?? I have a 3 story building and I'm not sure if I should use the MWFRS < 60 , MWFRS all h, or the alternate with h < 60 and C&C being 60<x<90...
Please advise.
Thanks.
