In recent years, the design criteria for vibration control are more strict. In this study, the dynamic characteristics of the slab is analyzed and the vibration is controlled for the special peculiarity of structures. First, the procedure of dynamic analysis is developed by the finite element method and then examined by using the slab model tests. Second, in order to improve the dynamic characteristics, the effects of the number of supports, material properties, position of exciting force, added mass and dynamic balance on the dynamic behavior of concrete slabs are analyzed. It is concluded that the vibration can be controlled by the change in the natural frequency of system and the use of the high-strength concrete or polymer impregnated concrete(PIC), and the dynamic characteristics can considerably affected by the arrangement of equipments, and added mass. etc.
