THE INELASTIC RESPONSE SPECTRA FOR STRUCTURES RESTING ON DIFFERENT SOIL SITES.

摘要

The present invention relates to a method for obtaining the normalized spectral acceleration for inelastic response for structures resting on diiferent soil sites. The Inelastic Response Spectra are for ductility factors 1, 2, 3, 4, 5 and 6 and pertaining to 5% damping. This invented inelastic Response spectra gives the value of normalized design spectral acceleration for inelastic response directly depending either on the natural time period or the displacement response of structures. One advantage of using this Inelastic Response Spectra for design of structures is that it takes into account the inelastic response of the structure (which is real) unlike the prior methods that take the elastic response of the structure (which is hypothetical), which will lead to a better. safe and economical design of structures.
