Level II input option requires an engineering review of the seismic response characteristics of the building by assessing those
issues likely to dominate its performance. These include configuration, continuity of load paths, compatibility of system
deformation characteristics, redundancy of load paths, strength of elements and systems, toughness of elements and connections,
and physical condition. The analysis based on the Level II inputs has moderately low levels of uncertainties.
The last level of investigation (Level III) is for engineers only, and it requires detailed structural input. Typical
calculations will involve such factors as story accelerations and inter-story displacements to estimate the expected damage
states. Highly insured buildings are the likely candidates for this more refined analysis. Level III analysis is not ideally
suited to general loss estimation software and will not be implemented here.
