Re: Elevator Loads

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

CBC is light on recommendations, it used to be 1998 CBC Appendix 30. The elevator manufacturers use the 1614A.1.15, or something similar. When you get their shop drawings the values match that derivation.

 

I still use 1614A for CBC and ASCE 7 applications.

Rick,
You noted CBC section 1614A.1.15, which implies DSA or OSHPD amendments.  Not having the code in front of me (actually I am at a Revit training class), is the section still applicable?  Thanks.

California BC 1614A.1.15modifies ASCE13.6.10 to read...

 

Design of guiderail support .... shall use the weight of the cab plus not more that 40% of it rated load, seismic forces shall be assumed to be distributed 1/3 to the top and 2/3 to the bottom guiding members, unless other data provided.

 

Seismic forces per ASCE 13.6.10.1, which takes you to 13.3.1, and specifies a minimum value of .5g.

 

Obviously for you primary frames and systems, elevator DL is absorbed in the building deadload and building base shear coefficient.

Hello,
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,

JJ
