Earthquake damage estimate method of fundamental structure, earthquake damage estimate system and earthquake damage estimate chart

摘要

PPROBLEM TO BE SOLVED: To provide an earthquake damage predicting method, an earthquake damage prediction system, and an earthquake damage prediction chart for a foundation structure for predicting and evaluating a standard of earthquake damage simply and quantitatively. PSOLUTION: In these earthquake damage predicting method and prediction system, subsidence of the ground obtained from earthquake damage data of an existing foundation structure is used as random variable, a fragility curve showing the relationship between the subsidence of the ground and probability that the foundation structure receives damage (hereinafter referred to as expression rate) is prepared, at least two damage modes expressing a state of damage corresponding to an objective of damage prediction or more are defined based on an angle of inclination of the foundation structure obtained from the earthquake damage data, and a fragility curve expressing the expression rate of each of the defined damage modes is prepared. A cumulative probability bar chart for cumulating and displaying the expression rates per damage mode based on the damage modes in order for optional subsidence of the ground is prepared to predict degree of earthquake damage of the foundation structure based on the prepared cumulative probability bar chart.
