Thanks for the encouragement. I have no intention of signing anything that leaves me exposed. I have already been (counter)sued... I know you can design a project to perfection and still become embroiled in a legal dispute. I told the client they should be worried about an engineer who would.

And thank you, Ron. I've endured webinars on contract language that weren't as informative nor concise as this looks to be.

Thanks, ron. I guess P.O.'s can be considered contracts? I didn't realize that.

Hi forum goers, I practice in the state of California, where to my understanding, everyone is supposed to work under a contract. Normally I work for owners or architects, but this is a job I thought I had already negotiated that is now in jeopardy because the client wants to work via purchase...

Much appreciated insight, thanks. Often us structural guys don't get much into the machining and fabrication process. It's not that testing isn't allowed per se, it's just that if testing is required to justify the assembly, it makes more sense instead to go welded, as much as the fabricator...

It would be shop fabricated. The client does a lot of machined non-structural work, but in this case, they need to carry structural loads. I'm not planning to stick my neck out, but before I tell them no, I felt like I needed to be sure I couldn't justify this connection via readily available...

Thanks, connectegr, That's what I suspected, but to satisfy my curiosity, do you know why the AISI specification couldn't be used? Many (most?) cold formed shapes are made out of A36 and it seems like it should be applicable. Also, I was thinking, if this particular connection (your...

hydtools: It would be a single row of fasteners, so I don't think eccentricity is an issue, but I don't see how fastening into the end of a 1/2" plate with a 3/8" fastener can work. dinjin: I'm responsible for the design. Is the AISI S100 the standard for screws? I've never worked much with...

Thanks desertfox. The strength of the screws themselves isn't the primary concern. How do you calculate the withdrawl value of a 3/8" screw into the edge of a 1/2" plate? I'm all but certain this isn't permissible, but then what is the edge distance requirement? My understanding is that screws...

Hi there. I usually only use screws for wood, wood/metal and steel/metal applications for situations I know how to solve vis-a-vis NDS and ICBO reports. I have a situation now for a steel-to-steel connection and I don't even know where to find resources. My particular situation is a client who...

hokie, I'm not entirely sure yet, either. Basically instead of just silicon/fin mullions, there's a threaded rod embeded. I believe this would be to support a canopy, but it was a typical detail, not just at the canopy locations. I may come back and post a detail in the next week once I see if I...

Wow, I'm a little surprised ISG hasn't installed any of them. At this point what I'm wondering about is the design of the vertical tension rods. The fins obviously need to be designed for tension loads for positive wind loads, so are the rods empirically designed to tighten the assembly? Or are...

Thanks for confirming that, hokie. Do you know if US jurisdictions accept facade designed with this code?

I'm wondering if there is any reference for how to design glass fin/steel rod supported walls. I have some background designing steel mast supported glass lites with spider connections, but not with these all glass type walls. It seems Australian Code AS1288 addresses this; would I find typical...
