There is a known complexity in calculating footfall response on irregular floors or staircases of any type. Footfall Analysis uses the RFEM model and the modal analysis results of RF-DYNAM Pro - Natural Vibrations to predict the vibration levels at all locations on a floor. A rigorous analysis method is essential to enable an accurate investigation of the dynamic behavior of the floor.
The software incorporates the most up-to-date analysis procedures, allowing the user to select between the two most often used calculation methods available; namely, the Concrete Centre Method (CCIP-016) and the Steel Construction Institute Method (P354).
