UBC verification for Pump
UBC verification for Pump
(OP)
Hi everyone, I work in a pump company in Italy.
A client now ask for a verification of a pump assembly ( motor + pump+ baseplate) as per UBC zone 1.
I don't know how to deal with it.
wich are the rules for the verification, if there si a classment of implants that prevent from a whole verifiaction fo the pump that for us is very onerous, mainly bacuase we don't have theinstruments ( ansys etc..)
Any advice on where to look in the UBC? or how to go on with the verification?
thank you very much.
Bye
Roberto

One option would be to calculate them for 1G and tell them to scale the forces appropiately for the support conditons they have.
RE: UBC verification for Pump
UBC (you have to buy the book) you need to get the earthquake acceleration with which to calculate the forces on the foundation. Depending on the pump type, you make a static or dynamic calculation. Normaly for the static one, there is a chapter for parts, that are not an essential part of the building (sorry, I do not have the code with me..). There is a formula with which you calculate the acceleration. It depends on seismic data (like the zone) and the height in the building, where the pump is mounted.
