Draft AS/NZS 1170.4 - Draft Number DR PPCD 8 - Floor height coeff.

Draft AS/NZS 1170.4 - Draft Number DR PPCD 8 - Floor height coeff.

Draft AS/NZS 1170.4 - Draft Number DR PPCD 8 - Floor height coeff.

(OP)
I have been using the calibration test version of the draft earthquake loading code for NZ and Aust, AS/NZS 1170.4 PPCD 8, Januay 2003.  

Re Equations 8.3(1) through to 8.3(3):

It is not clear to me whether the value for the Floor Height Coefficient CHi determined from Eqn 8.3(1) applies when hn (height from the base of the structure to the uppermost seismic weight) is less than 12 metres.  

Also whether for structures with hn < 12 m, above the level hi => 0.2*hn, is CHi the min or max of Eqns 8.3(1) and 8.3(3)?

Would appreciate hearing from anyone else who has been experimenting with this version of the draft code.

Not sure about your draft number, DR PPCD 8.  See https://committees.standards.com.au/COMMITTEES/BD-006/P....

Unfortunately DR 00902 (draft earthquake actions code) and DR 00903 (draft earthquake actions code commentary) are no longer downloadable from Standards Australia.

Good on the Kiwis.  Although hopefully not in this weekend RWC semi-final!

Will download, read and get back to you.
