RE: Elevator Loads

[Subject Prev][Subject Next][Thread Prev][Thread Next]



Just finish one for the cement plant providing an elevator used for transporting workers, equipment up to the top of the silo (160 ft). This elevator has an independent structure, wrap around with an access platform, and stairways.


Aside from the loads being provided by the elevator company, a close coordination also is required. One is for the no of access (entry/exit) and emergency stop (exit) requirements. Secondly, the anchoring system where the guide rail is mounted plays and important role in the design, transferring the magnitude of force to your structure.


I considered both live and dead in my seismic analysis noting that an earthquake can strikes even when the elevator is empty or full.

Subject: Elevator Loads


Would any of you be willing to share with me calculations of how to apply elevator loads to a building?  Do the loads have to be provided by the elevator manufacturer?  How does this work to incorporate them into my gravity loads and seismic loads?  Any information or hints you can give me about this subject would be greatly appreciated.

Thank you,
