Lateral resisting system for flat plate structure
Lateral resisting system for flat plate structure
(OP)
I am designing a flat plate parking structure with columns at 20 ft o.c. My problem is to define the lateral force resisting system. I am planning to use the cantilever column approach, does anyone know if this is allowed by the code? Is just that I read that it is not allowed for high seismic zones but I could not find the appropriate section in the code. What other system can I use if I want to maintain the flat plate system (no drop beams)?

You can do the pole situation if you use a grade beam system at the foundation for fixity. The connection at the top of the column could be pinned if you want. This is tanamount to an inverted concrete frame with a pinned base. Should not be a code issue.
No worries.

You can have an inverted moment frame that would mimic the cantilever column system. All you do is have a grade beam system at the foundation to establish the fixity for the column, and pin the connection at the top of the column. This should be allowable by code.
