Pier of bridge is usually used as a general term for any type of substructure located between horizontal spans and foundations.
Piers give vertical supports for spans at intermediate points and perform two main functions.
The objective of this study is to inspect the effect of piers shape on the dynamic structural performance by adopting theoretical dynamic analysis.
The results of dynamic analysis of 25 bridges models show that the maximum value of natural frequency is equal to 5.64Hz in two circles piers bridge model.
Therefore, this type of model has good stiffness and bearing capacity.
The two square piers model, the one circle pier model, and the two circles piers model appear good stiffness because of the natural frequencies (5.30Hz, 5.52Hz, and 5.64Hz) are more than the maximum forced frequencies (4.52Hz, 5.45Hz, and 4.52Hz) respectively.
According to the comparison between all models results, the two circles piers model has the higher stiffness because of this model has the maximum value of natural frequency (5.64Hz) and it is more than all forced vibration frequencies of all others models.
Therefore, this study recommends that using the bridge model of two circles piers in the bridges construction that consists of three spans (30m+40m+30m) with section of box girder.
