CADS Footfall Analysis is a post-processing software that can be used in conjunction with RFEM and RF-DYNAM Pro - Natural Vibrations providing footfall response analysis calculations. Footfall response is of interest to users concerned about the vibration induced in their structures due to walking related activities. As advances in structural design result in more efficient and lighter irregular structures, sensitivity to vibration of the structures is becoming increasingly significant.

Calculation methods:
  • Concrete Centre Method – CCIP-016 – A Design Guide for Footfall Induced Vibration of Structures
  • The Steel Construction Institute Method – SCI P354 – Design of Floors for Vibration: A New Approach

  1. Graphical Display of Answer

    Solution

    There is a known complexity of calculating footfall response on irregular floors or staircases of any type.
  2. Analysis input

    Features

    • Footfall Analysis links with RFEM, using its model geometry, so that the user is not required to create a second model specifically for footfall analysis
    • Allows the user to analyze any type of structure for footfall analysis, irrespective of the shape, material or use
    • Quick and accurate predictions of resonant and impulsive (transient) responses
    • Cumulative measurement of vibration levels – VDV analysis
    • Intuitive output enabling the engineer to improve critical areas in a cost-effective way
    • Pass/fail limit check in accordance with BS 6472 and ISO 10137
    • Available excitation forces: CCIP-016, SCI P354, AISC DG11 for floors and stairs
    • Frequency weighting curves (BS 6841)
    • Quick investigation for full model or specific areas
    • Vibration Dose Analysis (VDV)
    • Adjusting the minimum and maximum walking frequency as well as the walker’s weight
    • User-defined input damping values
    • Varying the number of footfalls for resonant response, user input or software calculated
    • Environmental response limit based on BS 6472 and ISO 10137
  3. Eigenmode mass participation graph

    Output

    • Overall maximum response factors and critical nodes
    • Resonant analysis (maximum response factor, RMS acceleration, critical node, critical frequency)
    • Impulsive (transient) analysis (maximum response factor, peak acceleration/velocity, RMS acceleration/velocity, critical node, critical frequency)
    • Vibration dose values for both resonant and impulsive analyses

    Charts
    • Response factor vs walking frequency
    • Mass participation vs eigenmodes
