Differential equations for out-of-plane vibrational motion of curved bridge under action of constant moving force are derived and solved with "method of initial conditions"; effect of torsional inertia is studied in free vibration solution and in forced vibration solution; parameters that describe behavior of horizontally curved bridge are radius of curvature and rigidity ratio; effect of changing either of these two parameters results in change of fundamental natural frequency of curved bridge; under passage of constant moving force, curved bridge is vibrating basically at its fundamental natural frequency.
