Earthquake response analysis equipment, seismic response analysis method and earthquake response analysis program

摘要

PPROBLEM TO BE SOLVED: To provide a seismic response analysis device, a seismic response analysis method, and a seismic response analysis program which can perform high precise seismic response analysis. PSOLUTION: When a seismic response analysis is performed by an operation part 16, using excess pore water pressure ratio and shearing rigidity of at least analyzed ground, at least one of the excess pore water pressure ratio and the shearing rigidity is derived in different rules before and after transfer to a cyclic mobility, when the ground is liquefied.
