Abstract

It is well recognized that Displacement Ductility Factor (DDF) could not be sufficiently efficient in structural earthquake- resistant design and other structural dynamic characteristics together with seismic parameters are required to be taken into account. In this paper, effort is made reasonably to determine Hysteretic Energy Capacity (HEC) of a SDOF system as cumulative damage parameter that the system sustains it in ultimate limit state. Low-Cycle Fatigue (LCF) concept and Coffin-Manson law employed for introducing a new energy based damage index. Statistical analysis on hysteretic energy in each half cycle used for obtaining HEC. Inelastic analysis results indicated that the hysteretic energy in each half cycle could be well modeled by the truncated Gamma distribution. According to the proposed energy based damage model, the dynamic HEC not only depends on structural characteristics, but is also related to the earthquake demands. Plots of energy-based spectra obtained from hundreds analysis and graph related to HEC calculation presented which can be used in energy based design approach.
