In this study, it is intended to compare the dynamic behavior of suspension and cable-stayed bridges for equal center span lengths. For this purpose, a suspension and a cable-stayed bridge with center spans of 1000 m are designed so that a realistic comparison can be made. Then, uniform and multiple-support ground motions are applied to the bridges to determine their dynamic responses. Nonlinear time history analyses are carried out for cases where the soil -structure interaction is taken into account and ignored. The results show that the multiple -support excitation as well as the soil-structure interaction generally increase the structural responses for both bridge models. On the other hand, depending on the uniform and multiple-support motions, the sensitivity of each bridge model is explored.
