Research on Energy Spectrum of Elastic SDOF
Abstract eng: According to the spectrum analysis theory the energy spectrum including input energy spectrum, damping energy spectrum, hysteric energy spectrum and kinetic energy spectrum of elastic SDOF subjected to earthquake had been obtained. 160 strong earthquake records were used to get the input energy spectrum in four site classifications. The results have shown that the input energy spectrum curve can be divided to three parts: the ascending part for short periods, the plateau part for moderate period and the descending part for long period. The site classifications have some influence to the plateau part. Simplified formulations for the three parts of the spectrum curve had been regressed. The rationality of the simplified formulations had been certified.
