METHOD AND EQUIPMENT FOR ANALYZING SEISMIC RESPONSE OF ASEISMATIC STRUCTURE

摘要

PROBLEM TO BE SOLVED: To enhance accuracy in the analysis of a seismic response of an aseismatic structure by employing a hysteresis characteristic model for an aseismatic unit which can represents the rising of initial displacement accurately and can perform simulation accurately regardless of the magnitude of displacement when seismic analysis is performed for the aseismatic structure born through the aseismatic unit comprising a rubber laminate where a plurality of rubbers and steel plates are laminated alternately and bonded through vulcanization, and a lead plug embedded in the center thereof. ;SOLUTION: Four spring slider elements 18a-18d comprising spring elements 16a-16d and slider elements 17a-17d connected in series, a single spring element 15, and a single dashpot element 19 are connected in parallel in order to set a hysteresis characteristic model for an aseismatic unit. A seismic response is analyzed for an aseismatic structure based on the hysteresis characteristic model thus obtaining a hysteresis characteristic model similar to an actual aseismatic unit having both characteristics of elasticity and plasticity.;COPYRIGHT: (C)1997,JPO
