Damage-Limiting Aseismic Design of Buildings

A procedure for earthquake-resistant design is developed to limit the potential damage of buildings to a tolerable level. The procedure is based on the damage model developed earlier (Park and Ang, 1984) in which structural damage is expressed as a function of the maximum deformation and dissipated hysteretic energy. The tolerable degree of damage is defined on the basis of calibration with observed damages from past major earthquakes. The design method is examined in the context of reliability.
