draft DZ TS 1170.5 Structural Design Actions

draft DZ TS 1170.5 Structural Design Actions

(OP)
Public comment now open on TS 1170.5, to help lead the way for new practices in seismic engineering

15 February 2024

The first draft of the hotly anticipated technical specification 1170.5 Structural design actions - Part 5: Earthquake actions - New Zealand is ready for public comment and we encourage all interested parties to have your say.

RE: draft DZ TS 1170.5 Structural Design Actions

There are some positive directions in the new code but equally it is increasing complexity
I've only done a very quick skim/talk to friends though so opinions TBC

I really like the rebranding of Ch(T) to Sas - feels like a more accurate depiction rather than some arbitrary coefficient label

The seven soil classes feels like a pointless pipe dream to be trying to push in, unless they're going to be supported by significant work from local councils prior to citing it in the Building Code.

Tabulating all the acceleration parameters is nice but will be a headache for incorporating into existing spreadsheets
Also going to be a nightmare when you're working in an area outside of the named areas due to lack of a picture showing the values
Google Earth overlays with the different return periods and contours would help a lot

RE: draft DZ TS 1170.5 Structural Design Actions

Thanks for the public announcement!

Hmm... i just a quick keyword search for pESA method being the way to load up diaphragms. I wish the updated 1170.5 would draw a straight line between diaphragm design actions and an equation. It doesn't do that. I get there's commentary, but it's just that, commentary.
If you look at ASCE codes, it has the Fpx equation.

...anyone have thoughts on this?
