Question 1 (35%)
A bridge is sitting on top of four piers as shown in below. The bridge is subject to a ground motion as a result of an earthquake.
Assume the ground displacement is modelled as a harmonic loading ug (t)= U0sin(ഥ(w)t) with U0 being 0.5m.
The mass of the bridge deck is Mdeck = 6×106 kg. The piers have a circular cross section with a height of L=10m, and a radius of 3m.
Consider an elastic modulus of E = 20 GPa for the piers
(1) Plot the time response of the bridge for 10 seconds under the loading if ഥ(w) = 2/wn where wn is the natural frequency of the bridge.
(2) Determine the maximum bending stress at the bas
