METHOD AND SYSTEM FOR EVALUATING LEVEL OF DAMAGE TO RC MEMBER

摘要

PROBLEM TO BE SOLVED: To efficiently evaluate a level of damage without the visual observation of a column. SOLUTION: An arithmetic processing part 3 provided in a damage level evaluating system 1 includes: a member angle computing part 6 which determines a maximum response member angleθa based on measured data from a peak sensor 2a or the like; a conversion part 7 which converts the maximum response member angle to the observation horizontal displacementδa or the like of a rigid-frame viaduct; a dynamic nonlinear analysis part 8 which determinesαa or the like at each rigid-frame viaduct as a magnification ratio in which dynamic horizontal response displacement almost conforms to the observation horizontal displacement; a compensation coefficient evaluation part 9 which evaluates an input earthquake motion compensation coefficientλby which observation earthquake motion is multiplied according to the magnification ratioαa or the like; a correction earthquake motion development part 10 which obtains corrected earthquake motion by multiplying the observation earthquake motion byλ; a dynamic nonlinear analysis part 11 which calculates the dynamic horizontal response displacement of the rigid-frame viaduct corresponding to the corrected earthquake motion; and a damage evaluation part 12 which evaluates the damage level of the rigid-frame viaduct using the dynamic horizontal response displacement.
