Discussion

A single-degree-of-freedom idealisation is reasonable for

  • A.a structure with several closely spaced natural periods
  • B.a water tank on a slender staging
  • C.a twenty-storey moment frame with setbacks
  • D.a long irregular building with a flexible diaphragm

Answer: B

Nearly all the mass sits at the top of the staging and the structure has one obvious sway direction, so one degree of freedom captures the behaviour. Tall or irregular buildings need many degrees of freedom to be represented properly.
