Are structures to remain elastic under wind loading? 16

[amengr]

Just a quick question as I am new to wind engineering. For the MWFRS are the wind loads we calculate per ASCE7 such that we are designing the structure to remain elastic or is it similar to seismic design where we allow structures to develop plastic hinges/deformation?

A very interesting chat about MWFRS design and serviceability. The discussion about ductility in the ultimate strength design is in the commentary Q&A at the end.

If you don't already receive notice of ATC's free webinars, I would encourage you to sign up.

This is a great discussion. I'm a big Chris Letchford fan - so I'm biased - but I found the compilation of all this material and the discussion around it quite compelling.

I need to noodle on it a bit further - but my takeaway was that since human perception and envelope performance are key in wind design - purposefully designing a building system (or its components) to undergo plastic deformation to meet a strength limit state...doesn't feel like the best idea.
