It seems that there is a huge hole in the practice of design and supply of manhole riser sections that have holes in them. Granted, when there are no holes in a manhole riser, the math shows that the riser sections have plenty of strength. Now then what really happens inside a riser when we...
Is anyone aware of file sharing websites for TEDDS for word files? I am aware of SteelTools.org. Is anyone interested in setting up a TEDDS file sharing pool?
The previous thread: thread176-347025 cleared up a lot of the requirements for this. Regardless, I wanted to check to see what people do with the load case 1.2D+1.6S+.5W. I have three snow cases; balanced, drift right, and drift left. I have eight wind cases. So.... I need 24 conjugations to...

Just thought I'd leave eng-tip on this. To recap we're talking about designing circular concrete beams for flexure only. CRSI has tables that show phiMn (moment capacity)for a circular section. Unfortunately the tables don't have reinforcing on the low end. The tables are...

Note that there is a new UFC out for ATFP. Does anyone know how to interpret B-3.1.4.1 with respect to the tributary area increase factor? My only guess as to what this means is that the whole wall should be loaded with blast pressure just like wind. Meaning the trib...
When a base plate sees more shear than available friction, what actually happens? Certaintly the anchors go into bending. After some deformation would it not be reasonable that a concrete wedge forms as shown in the following sketch? Wouldn't that in turn add to the friction available?
Does...
Hello all,
I am designing double channel bracing for a project. Has anyone seen or developed a spreadsheet for this?
No, I'm not looking for the way around learning the specification. I am a seasoned structural engineer trying to make a profit by using as much shareware as possible. I...
Are commitee members paid for their efforts? Should they? How much would this inflate the cost of our codes?
Do the code commitees require a portion of the commitee to be practicing engineers? Should they?
Would you rather photocopy or otherwise illegally copy our overly complicated codes...
Does anyone else view appendix D as a poor code?
Let's take a poll;
How many people use a simpler, or older anchor design routine?
How many people actually use Appendix D?
I wrote this spreadsheet for beam-column tube design following AISC 13th. I accept no liability for your use of this. If you do check it/use it please make note of any problems.
