Minimum allowable frequency of a structure - Eurocode provision?
(OP)
Hello everyone, i am designing a two storey RC Frame house according to Eurocode. My question is, is there any EC8 provision that sets a minimum for the fundamental frequencies for certain types of structures?
if not, then what is your advise?

Thanks for your reply
are you referring to the interstorey drift sensitivity coefficient?
EC8-1: 4.4.2.2 (2) Eq. 4.28
θ = (Ptot x dr) / (Vtot x h) ≤ 0.1

However, I was talking specifically about the damage limitation requirements that need to be satisfied with the limitation of the interstorey drifts (4.4.3.2). These will probably govern your design if your structure is too flexible.
