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. 000011865 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000011865 653__ $$aelastic SDOF, energy spectrum, four site classifications, simplified formulations 000011865 7112_ $$a14th World Conference on Earthquake Engineering$$cBejing (CN)$$d2008-10-12 / 2008-10-17$$gWCEE15 000011865 720__ $$aTeng, Jun$$iDong, Zhijun 000011865 8560_ $$ffischerc@itam.cas.cz 000011865 8564_ $$s241281$$uhttps://invenio.itam.cas.cz/record/11865/files/05-01-0579.pdf$$yOriginal version of the author's contribution as presented on CD, Paper ID: 05-01-0579. 000011865 962__ $$r9324 000011865 980__ $$aPAPER
