SEISMIC DEMAND BASED ON DAMAGE CONTROL MODEL - CONSIDERING BASIN EFFECT AND SOURCE EFFECT

The Park and Ang damage model was used as the ''Structural Damage Cont rol Model'' to study the seismic design parameters. This damage contro l model included the displacement ductility and hysteretic energy in t he analysis of elastic-perfect-plastic single-degree-of-freedom system . Based on this damage control model, the reduction factor and yield b ase shear coefficient are discussed. Seismic data collected from Taipe i basin were used to examine the code-provided yield base shear coeffi cient which reflects the influence of using a damage control model in the seismic design parameter. Effects of seismic source as well as Tai pei basin topography are also considered in examining the variation of yield base shear coefficient. (C) 1998 Elsevier Science Ltd. All righ ts reserved.
