Abstract

Since the natural frequency and damping ratio of the light weight steel floor are lower than those of the reinforced concrete floor, the floor vibration due to a dynamic load is significant and the serviceability issue becomes more critical. In this paper, the floor vibration performance of the light weight steel floor is evaluated for different design factors. The impact loading test and walking test were performed on the floor specimen built with different design factors. The acceleration data obtained from tests were analyzed to obtain the natural frequency and damping ratio of the specimen, and the effect of design factors on the floor stiffness and vibration are evaluated. Further, the effect of variables of walking test method on the floor vibration performance is also evaluated. The floor vibration performance is evaluated using AISC design guide and AIJ design guide. The results indicate that the connection between the upper and lower beams due to wall construction increases the stiffness and the natural frequency of the entire floor and thereby improves the floor vibration performance. However, the installation of floor heating system and furniture do not effect on the floor vibration performance considerably. Copyright
