Fundamental Frequencies of Vibration of Footbridges in Portugal: From In Situ Measurements to Numerical Modelling
Figure 4
Frequencies of 1st mode in the three directions (T, L, and V) as a function of largest span: (a) to (c) all typologies for V, T, L, and (d) V + L; (e) to (h) vertical for steel box-girders, truss structures, RC structures, and other structures, respectively. Red curves are explained in Section 3.3.
