Building Damage Assessments
Specific Building Damage Assessment is calculated using the Burland (1997) assessment method. Buildings are specified by their locations and bending properties. XDisp uses the analysis data to class the buildings into damage categories based on their tensile strains.
Generic Building Damage Assessment avoids detailed assessment of large numbers of buildings which are later found to experience damage within acceptable limits. The same assumptions and calculation methods which would be used for individual specific buildings are applied to representative sections transverse to a defined route. Along each section a number of different building geometries are analysed and the worst cases are assessed against standard criteria.
Utility Damage Assessment
Specific Utility Damage Assessment is calculated by assessing the extent of rotation of joints, pullout of joints and axial and flexural strains. Utilities are specified by their locations, dimensions and acceptance criteria for rotation, pullout and strain. XDisp uses the analysis data at joints and reports whether the rotations, pullouts and strains calculated at joints satisfy their respective limiting criteria.
Generic Utility Damage Assessment is similar to damage assessment of Generic Buildings. Generic Utilities are assessed by applying the specific utility damage approach to representative sections along a route using different utility properties and diameters.
Rail Damage Assessment
Assess vertical displacement, Cant, Twist (both short base and long base).
