Hi All,
We are designing a large internal ground-supported piperack structure for an industrial facility located within Europe in a seismically active region,
The piperack system carries mechanical piping and electrical cabling and is a sizeable structure,
There are 15No. piperacks located at the ground floor level of this single-storey structure.
Each piperack structure is approximately 60m in length and the piping on the 15NO. racks bridges between each rack also.
The racks are designed with modular offsite construction in mind and a light-weight steel frame carrying the services will sit on top of hot-rolled structural steel framing beneath, with columns spaced at approx 5.0m centres, the racks are circa 7.0m in height
My query is this;
When assessing and designing this structure for seismic design requirements;
Is it sufficient to design the frames of this rack system as a Non-structural element supported at ground slab level in accordance with EN1998 or should the design of the structural steel frame be undertaken as if the steelwork was a building structure (essentially an unclad steel building supported from a raft foundation (ground bearing slab))
I believe the resulting foundation forces will be considerably different dependant on which option is chosen
Any thoughts on this would be appreciated
Regards
