Updated version of the calculation model with the following changes:

  • Removal of focus on Greening paper, column usage replaced by values which are constant.
  • Inclusion of conservation of momentum energy loss for usage in subsequent deformation of materials.
  • Specific floor heights used, rather than an averaged constant.
  • Concrete crush scale maximum removed. Unlimited scale permitted.
  • Manual concrete crush scale ramping parameters removed.
  • Impact KE based concrete crush scale calculation added. Switchable.
  • Floor-by-floor concrete crush volume percentage added.
  • Floor-by-floor mass loss (kg) added. Switchable.
  • Per floor Impact KE based mass loss calculation added. Switchable.
  • Calculated mass switchable to include/exclude cap mass loss.
  • Initial cap drop height modifier added.
  • Average Debris Lateral Ejection Velocity included.
  • Debris Lateral Ejection Energy Requirement Added. (Applied to mass lost)
  • Concrete mass inside core uses floor-by floor specific area percentage modifier to account for variation in usable floor area.
  • Graphs for tracking Kinetic Energy, Mass and Velocity.
