EVALUATION DEVICE, EVALUATION METHOD AND EVALUATION PROGRAM FOR EARTHQUAKE DAMAGE LOSS OF BUILDING

摘要

PROBLEM TO BE SOLVED: To perform a series of calculations from an earthquake extraction to a calculation of a PML value by one information processing apparatus, and calculate the PML value with accuracy considering an amplification characteristic of an earthquake motion according to the multilayer ground at the level of a general PC.;SOLUTION: Earthquake extraction means 1 extracts information on an earthquake center dislocation and the earthquake from a database 9 and prepares an acceleration response spectrum on the foundation of the ground on a construction site according to a distance attenuation expression. Ground amplification factor calculation means 2 models into two layers of the uniform surface layer ground and the foundation from information on the multilayer ground and determines an earthquake motion amplification factor specific to the surface layer ground. Response analysis means 7 models a building, determines a strength spectrum, determines a ground surface response spectrum from the acceleration response spectrum and a surface layer ground amplification factor and determines response displacement and response acceleration of the building from a relation between the strength spectrum and the ground surface response spectrum. Loss/PML calculation means 8 calculates a PML value using the response analysis result.;COPYRIGHT: (C)2013,JPO&INPIT
