Özet
In this study, the parameters affecting the dynamic behavior of flexible structures under the influence ofmultiple vehicle passages are examined in detail. The flexible structure considered in the study is considered as abridge girder with simple supported boundary conditions which modelled according to Euler-Bernoulli thin beamtheory. The equations of motion of the bridge beam in contact with the vehicle passing over the bridge wereobtained by using the Lagrange equation after the kinetic and potential energies of the system were obtained. Thesecond-order differential equations representing the motion of the system are transformed from the first-order statespace matrix representation to the first-order state using the state variables specified in the study. The system ofdifferential equations is then solved with high accuracy using a special program prepared in the MATLABcommercial software using the Runge-Kutta algorithm from the fourth degree in the time domain.
