Seismic Damage Model for Regular Structures

International Journal for Engineering Modelling, 2001
Seismic damage model of regular structures is analysed. It is based on following assumptions: Seismic response of regular structures (symmetric plans and constant vertical stiffness) can be well interpreted by using SDOF system as a mathematical model of the structures. Response parameters of structure as ductility, stiffness change, energy balance and
