The short answer is no - for many reasons. A few of them: - How would you define g, the transverse center-to-center between fastener gage lines? Welds do not have gage lines. - How would you define s, the longitudinal center-to-center spacing of any two consecutive bolt holes? Welds do not...

Oof - I think this one went WAY off the rails on the sphere. The sphere is strictly for sizing of openings (at least in the US) and the designer is not intended to try and ram it through. The cable must take 50 plf or a 200 lb point load laterally. Interestingly, IBC Section 1607 does not...

SRSS is definitely the way to go, but your question raises other questions: - Are you trying to design a connection that will let the two buildings move independently of each other? - Will you tie them together and prevent relative motion in just one direction, NS or EW? - Will you tie them...

@RattlinBog It was pretty tough. I'm not sure I did very well. Not having tabbed books next to you is a definite hindrance. I spent too much time going through the PDFs... @phamENG Yes, I entered the AISC contest and won one! I'm featured in the February issue of Modern Steel Construction...

I happen to have a spare 16th... :) -5^2 = -25 ;-)

I just took the SE depth (very first CBT version of it) and I used the 16th to study. Won't matter a bit... -5^2 = -25 ;-)

ASCE 59 gives the limit state load combination of 1.0DL + 1.0LL + 1.0BL as the only combination to be used. It then says we are to adjust live loads and dead loads based on whether they help resist the blast load or add to it. That I understand. What I am trying to nail down is whether this...

Picked up a 48SX and 2 years later upgraded to the GX in college. Now use a 48G (only accesses 32k of RAM instead of 128k - much faster). It's on my desk and used often for two reasons: 1. It is great to bang out some quick numbers to get in the ballpark before getting serious on the...

Any code reference for something like that? -5^2 = -25 ;-)

Not a bunch. It's more for construction ease than anything else. The anchors near where the beams intersect the channel will take 99% of the load. -5^2 = -25 ;-)

We have a case where we are anchoring the back of a channel to a concrete wall, then attaching several steel members perpendicular to the channel. Is there a maximum spacing between anchors that we should use? I don't like the idea of a long span of the channel not stitched to the wall. For...

If you can get hold of a CEMA "Belt Conveyors for Bulk Materials" it will have the values used for bulk handling which are pretty well defined. I can't put my hands on my CEMA right now, but if you find even an old one, it would help you. -5^2 = -25 ;-)

Thanks for the feedback. We commonly have not left any gap there. So that we don't belabor the point with the client, we'll be moving ours up... -5^2 = -25 ;-)

There has been a back-and-forth in our office and with a client engineer about resting the bottom layer of a pile cap's reinforcement directly on top of the piles. To be specific, we have a 2'-6" thick pile cap with 24" pipe piles sticking up 4" and a 1/2" cap plate on them. We are showing...

dik, Try as I might, I am not able to decipher it. Sorry... -5^2 = -25 ;-)

Dik - I poked around, but don't see a pm section on this site. milkshakelake - I can certainly print it out, but three ring binders are slow to flip through. -5^2 = -25 ;-)

Throwing this one out there - does anyone in south Louisiana have an ASCE 7-16 I could borrow until after October’s SE? I found out that there are some esoteric items missing from the 7-10 I’m using. Thanks! -5^2 = -25 ;-)

Thank you, bugbus! Star for you! Those pictures were really throwing me for a loop structurally. It's frankly amazing how much money flows through Formula 1. Those are some very nice temporary grandstands and they are not even on pit row! -5^2 = -25 ;-)

DaveAtkins, Look closely - the upper floors are all steel, and the bottom floor is scaffolding. If it was to be wood frame, wouldn't the lower floor already be framed up? Also, if you needed portal frames, isn't the greatest need for them at the lower floor? I just can't fathom why you would...

I was thinking the same thing about pouring some sort of concrete foundation, but that raises all sorts of questions: why not pour the concrete first (as practically every other structure has done)? Are you going to encase your scaffolding columns? What about the scaffolding joists that tie...
