Seismic response analysis equipment, seismic response analysis program and seismic response analysis method

摘要

PROBLEM TO BE SOLVED: To provide an earthquake response analysis device, an earthquake response analysis method, and an earthquake response analysis program that perform earthquake response analysis of high accuracy.SOLUTION: An arithmetic part 16 when performing the earthquake response analysis using at least an excessive gap water pressure rate and shear rigidity of the ground to be analyzed derives shear rigidity using a function predetermined such that a calculated value is smaller as shear strain increases before transition to cyclic mobility when the ground is liquefied, and larger as the shear strain increases after the transition to the cyclic mobility.
