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.
