Structures Modeled by Generalized Coordinates of all parts of the system. These coordinates are usually called .. Their number is equal to the number of degrees of freedom in the system. When the system has only one degree of freedom, the configuration of the structure is determined in terms of a single generalized coordinate.

Structures Modeled as Single-Degree-of-Freedom Systemsriate model permits the reduction of the number of degrees of freedom to a discrete number and in some cases, to just a single degree of freedom. Fig. 1.1 shows a one-story building which may be modeled with one degree of freedom.

Seismic Response and Design Spectractra are presented in Sections 2.4 and 2.5. The influence of local soil conditions is treated in Section 2.6 and corresponding methods for the construction of spectra are presented in Sections 2.7 and 2.8. Section 2.9 introduces recent advances in the construction of response spectra using predictive attenuation relationships.

Australia Most of the events recorded during this period, from 1897 to 1972, corresponded to earthquakes of relatively low magnitude with only a few quakes of magnitude just over five (. > 5) on the Richter scale.
