New - Footfall assessment of floor vibration to CCIP-016

A new option is added to perform Footfall analysis following the method of the UK Concrete Centre Design Guide A Design Guide for Footfall Induced Vibration of Structures (Reference CCIP-016). The CCIP-016 design guide is applicable to structures of any construction material, e.g. steel, composite, concrete or timber, making it a highly flexible option applicable to all kinds of buildings. This feature was first introduced in release 2023 Service Pack 1.

For this new method the settings, input parameters and overall workflow are essentially the same as for the existing SCI P354 option. For more in depth details see the Help Topic Footfall assessment handbook and eLearning Course Footfall assessment in Tekla Structural Designer.

As part of this update, the “Footfall Assessment Results” group of the Footfall Analysis ribbon has also been slightly reorganized - the Envelope, Response Type and Pacing Frequency controls are now placed to the left of the controls for viewing Response Factor, Rf and No. of Events etc, as shown in the picture below.

  • New Settings - for the new Design Guide option a new set of Footfall Assessment settings “CCIP-016” is added to Global Settings as shown in the picture below. These set the initial Footfall Assessment options and parameters for new models. The settings options and initial defaults for CCIP-016 are the same as those for the existing SCI P354 option and so are not discussed further here.

  • Workflow - Essentially the key difference in workflow to the existing SCI P354 option is to select the new “CCIP 016” Design Guide option when creating or editing Footfall Analysis Models (FAM), as shown below.

    • The new “CCIP 016” Design Guide option can now be selected on the Footfall Analysis Ribbon prior to creating a FAM.

    • In the Footfall Analysis > Settings dialog there is now a new set of “CCIP 016” settings which can be selected, reviewed and edited.

    • The CCIP 016 Design Guide and associated settings set can also be set in the Properties window when creating or editing a selected FAM.
  • Notable Differences vs SCI P354:
    • Vibration Dose Value (VDV) - when working to CCIP-016 a VDV assessment is only allowed for the Resonant response - it cannot be used to assess the Transient response. Hence, where the Transient response is considered for a FAM and governs, the VDV results will not override the overall Pass/ Fail status with “Consider VDV for Pass/Fail” enabled. For more about this see the new Help Topic Footfall analysis basic workflow - CCIP 016.

    • Results - there can be significant differences in the footfall check results from the CCIP-016 method vs those for SCI P354. In short, they are different methods and so should not be expected to give identical, or even necessarily comparable, results in all cases. For more on this see the note at the beginning of the Help Topic Footfall analysis limitations and assumptions.
