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.
