Report on Loma Prieta Earthquake (October 17, 1989)
The report describes investigations of the October 17, 1989 Loma Prieta Earthquake made by Technical Research Institute, Obayashi Corporation. The topics focused on for discussion are as follows: Orthotropy in attenuation relationships, frequency characteristics according to spectral analyses, directionalities of ground motions and waves from the epicenter; Liquefaction potential of Marina district based on the survey of existing boring logs and liquefaction tests; Damage observation based on a bent-by-bent survey, dynamic characteristics of the ground, ultimate strength and elasto-plastic behavior by FEM analysis and dynamic response up to failure by two-degrees-of-freedom system analysis based on the FEM analysis results regarding the Cypress Viaduct; Comparison between the results of response analysis and the investigated data based on the recorded strong seismogram of a base-isolated bridge.
