Evaluation method for earthquake resistance of houses

摘要

PROBLEM TO BE SOLVED: To provide a method for evaluating earthquake resistance of a house with an improved evaluation accuracy by adding the ground on which the house is built as an evaluation element. SOLUTION: A step of performing a microtremor survey on a building ground of a house to calculate a surface ground amplification factor of the building ground as a site surface ground amplification factor 14, and an amplitude component of seismic motion data at an observation point of a predetermined past earthquake. To calculate the reference ground motion data 1 by dividing by the surface ground amplification factor 11 at the observation point of the past earthquake, and to calculate the site expected earthquake motion by multiplying the reference ground motion data 1 by the site surface ground amplification factor 14. And a step of evaluating the seismic performance by inputting the site expected seismic motion into the seismic evaluation device 2 as an input value. [Selection diagram]
