文摘

Increased deflection and dynamic stiffness were observed under long-term loading. Material properties of the resilient materials were measured for more than 500 days and used for the proposed equation. The relation between dynamic stiffness and deflection can be easily and reliably predicted using the proposed equation. Increases of the floor impact sound level after ten years were observed in most of the loading cases. It was able to understand both the serviceability and structural capacity of the resilient materials in this study.
