Seismic Design Category D Connections

Seismic Design Category D Connections

Seismic Design Category D Connections

I have been asked to design the beam to beam connections and beam to column connections for a new project that is located in Seismic Design Category D. I have review ASCE 7-10 and Seismic Provision 341-10. My understanding is that for the beam to beam connections I can basically use single shear typical connections. but for the bracing I will have to add some over strength factors and make adjustment.

Anyone have any tips? or comments that I need to review. I have never designs an heavy industrial building in this Seismic Zone.

RE: Seismic Design Category D Connections

Get a copy of the Seismic Design Manual. Not just the free AISC 341 available online, but the entire physical book. Go through the examples, they're extremely detailed and step through pretty much everything you need to check for each SFRS type.

In my opinion any structural engineering office doing seismic design of steel structures under US codes should have a copy of this. No exceptions.

RE: Seismic Design Category D Connections

Agreed, the seismic design manual was my guide for both studying and during the SE exam. As someone who doesn't do high seismic design in day to day work it's the best reference I found.

X3 for the SDM recommendation. Among other things, it's one of the best connection design references that I know of. You can also find some exellent, free information in the NEHRP design briefs: Link

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

RE: Seismic Design Category D Connections

Steeltips has a good example.

RE: Seismic Design Category D Connections

Thank you all for your helpful tips. I will get a copy of the physical book. All I had was the free online version.

eBook - Rethink Your PLM
A lot has changed since the 90s. You don't surf the Web using dial-up anymore, so why are you still using a legacy PLM solution that's blocking your ability to innovate? To develop and launch products today, you need a flexible, cloud-based PLM, not a solution that's stuck in the past. Download Now
White Paper - Using Virtualization for IVI and AUTOSAR Consolidation on an ECU
Current approaches used to tackle the complexities of a vehicle’s electrical and electronics (E/E) architecture are both cost prohibitive and lacking in performance. Utilizing virtualization in automotive software architecture provides a better approach. This can be achieved by encapsulating different heterogeneous automotive platforms inside virtual machines running on the same hardware. Download Now
