Thanks, Agent666,
Hmm, certainly no chance in this instance (wind-governed 20-storey RC building with 300mm thick lift/stair cores and use of some perimeter shear walls) of getting a clear split between sway x / sway y and torsion modes across the first three fundamental modes without any other...
Hi All,
Given there is yet to be a commentary released for the above code, seeking clarification for Clause 6.1 a) "whenever significant coupling is evident in the first three modes of vibration":
1. Assuming "significant coupling" pertains to some sort of torsional mass participation and/or...
