Seismic return period reduction for amusement structure 1

[atrizzy]

Does anyone have a reference (preferably Canadian, but I'm not picky) as to a typical reduction in seismic return period for amusement type structures (think water slides, roller coasters, go-kart tracks, etc).
Canadian Code requirement of 1/2475 yrs, as required for buildings seems pretty strict.

Thanks very much in advance.

If it is permanent, then it should be same as the building next door. If it is a temporary structure like a moving carnival I could see you use a lower return period. When we engineer these we use the standard ASCE 7 (US code I know...) period for these structures as they will last 25 years without significant repairs and then repaired to get to longer years.

Plus let's be honest, is that fatigue style structure something you really want to barely pass lateral loads? what if it has 10% loss in material due to exposure will it fail? not the type of structure to skimp on IMHO.

Given the dead load of such structure is quite low and the live dynamic load and wind load is quite high I would have thought that seismic actions are unlikely to be a dominant factor in design.
