Title:
SEISMIC RESPONSE ANALYSIS METHOD
Document Type and Number:
Japanese Patent JP3847264
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a seismic response analysis method capable of providing a simple and accurate seismic response of a ground-pile-building compound system in consideration of a difference in excess clearance hydraulic pressure between a free ground and an inter-pile ground.
SOLUTION: The shearing force Kp (Γp) of the ground spring of the inter-pile ground is obtained by using the inter-layer displacement Γp of a pile, the shearing stress τp of the inter-pile ground is obtained by using the shearing force Kp (Γp), a cumulative degree of damage Dp of the inter-pile ground is obtained by using the shearing stress τp, and an excess clearance hydraulic pressure rate Ru_p is obtained by using the cumulative degree of damage Dp. The effective stress σm_p of the inter-pile ground is obtained by using the excess clearance hydraulic pressure rate Ru_p, the initial rigidity Kpfo of the inter-pile ground spring is obtained by using the effective stress σm_p, and an interacting force Kpf (Γpf) between the inter-pile ground and the free ground is obtained (steps S20 to S27).
