The events occurring in silos which are classified as special engineering structures from construction and usage point of view are too complicated to solve with simple equations and perceptions. On the other hand, it is quite clear that they also have to be designed for earthquake loads to provide a required safety by the codes. However, it is known that this type of structures is damaged beyond the acceptable damages. This case might be attributed to the calculation methods used in their designs if no mistakes were made in construction processes. Therefore, the main purpose of this study was to investigate the behaviours of cylindrical reinforced concrete silos with analytical methods, added mass and Lagrangian approaches and to compare the results of these methods. While comparing to the results of analytical methods and added mass approach, the results obtained indicate that isoparametric element chosen by the Lagrangian approach can successfully be used in earthquake analysis of silos when sloshing effects are ignored.
