Frame Requirements

(OP)
Do column lateral resisting elements of a CANTILEVERED COLUMN BUILDING SYSTEM have to satisfy the ductility requirements for frames? Why?

RE: Frame Requirements

According to Section 1628 of UBC 97 "R" is numerical coefficient representative of global ductility capacity of lateral force resisting systems.

For Cantilivered Column Building Systems R = 2.2.

It will require to design this structure for loads 4 times larger than Special Moment Resisting Frame (R = 8.5).

By using this coefficient every system (with different ductilities) should be able to take requred load.

Is this what you are after?

RE: Frame Requirements

(OP)
Sorry, what I meant is the conformance of the special seismic detailing of the cantilever column elements as specified in 1997 UBC, Section 1921.4, "Frame members subjected to bending and axial loads."
