Lake06 et. al. If you are looking for a quick online resource for steel beam design, check out WebStructural.com. You can quickly size steel beams for using AISC ASD or LRFD design criteria. I have found it to be a very helpful tool. Many some of you will as well. Check it...

I spoke with the developer of this program. It sounds like it is no longer supported at the site I provided above. Plus there were a few bugs which are still present. Use the link below now... http://www.webstructural.com/ The developer has expanded the module so you can also save files...

Thank you for all of your responses. @JAE: I guess I've always used the IBC to dictate what non-lateral deflection limits I use on rafters, beam, joists, etc. But was thinking the other day about the difference btwn. the code and what people are doing in practice. (Obviously IBC is a...

I have a question regarding Structural Deflection Limits. The way I see it, there are three ways of going about it - Follow the IBC verbatim, or use ASD load combinations, or load that aren't factored at all. For example: What are the appropriate combinations to used if I have both a floor...

eit09 - I took a look at your example and from first glimpse you seemed correct, but hef for you problem is actually 4" according to D.5.2.3 and therefore equation D-8 wouldn't apply. At least thats my interpretation.

JAE - Can you give an example problem. I've found it checks well with ACI code. Even modifies hef and ca1 per D.5.2.3 & D.6.2.4 respectively. Maybe that is where your discrepancy is arising (if your close to 3 of more edges) - I've got no idea without an example, but running though some ACI...

FYI: If anyone is looking for a Free and Helpful tool for ACI Appendix D calculation check out the attached link. I have found it helpful in running quick checks as well as documenting calcs. - Plus its completely free, and no downloading anything. Let me know what you think...

Ultimately, my question is: Can I prevent concrete Pryout with properly designed (fully developed and sized) supplemental reinforcing in the vertical (Tensile) direction? In the article you provided (Page 4, Item 4): "When reinf. is used to restrain concrete breakout, the overall anchor should...

I'm in the process of designing some pilasters with fairly large loads and am planning to design supplemental reinforcing to prevent concrete breakout. The problem that is arising for me is that pryout is controlling shear failure. My interpretation of the code is that supplemental reinf. is...
