Structural vibration 1

[sspkee]

I have a 30m span composite floor (steel beam with precast plank & topping) to be designed and would appreciate someone can advise me in the forcing frequency for Fibration Design of Floor Structures.
A range of value is suggested in NBC 1995 Cananda Code. However what is the appropriate forcing frequency for
a.) Ball room
b.) Pleanary Hall that for speeches and music events (not for pop concert)
c.) any reference for the suggested values?

Thank you
