Abstract

A methodology for characterizing the different levels of incident motion for micro zonation is discussed. Relatively long period components, which dominate the nonlinear response of soft sites at higher level of excitation, are suitably accounted for. Incident motions with the defined characteristics are generated by two step iteration scheme, and a seismic micro zonation example based on the nonlinear response analysis of a soil profile database system is presented. Effectiveness of a new micro zonation parameter, defined as Spectrum Intensity Amplification (SIA), to represent the extent of ground shaking hazard is examined and is found to represent well the damage pattern of wooden houses during a past earthquake.

Seismic Microzonation Considering Long Period Components

St. Louis, Missouri

A methodology for characterizing the different levels of incident motion for micro zonation is discussed. Relatively long period components, which dominate the nonlinear response of soft sites at higher level of excitation, are suitably accounted for. Incident motions with the defined characteristics are generated by two step iteration scheme, and a seismic micro zonation example based on the nonlinear response analysis of a soil profile database system is presented. Effectiveness of a new micro zonation parameter, defined as Spectrum Intensity Amplification (SIA), to represent the extent of ground shaking hazard is examined and is found to represent well the damage pattern of wooden houses during a past earthquake.
