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 visual observation of a column.;SOLUTION: A system 1 for evaluating the level of damage includes peak sensors 2a, 2b and 2c, and a computation section 3 which performs the computation of measurement data from the peak sensors. The computation section 3 includes: a member angle computing section 6 which determines a maximum response member angle θ from the measurement data from the peak sensors; a conversion section 7 which converts the maximum response member angle to an elastic response displacement δ using elastoplastic characteristics including an equivalent natural period T_eq of a rigid frame viaduct 4; a response characteristic computing section 8 which determines the elastic response characteristics of a structure group 21 using the equivalent natural period T_eq and the elastic response displacement δ; an elastic response computing section 9 which computes the elastic response displacement by applying the equivalent natural period T_eq of the rigid frame viaduct 4 as a non-measurement object to the elastic response characteristics of the structure group 21; and an inverse conversion section 10 which converts the elastic response displacement to the maximum response member angle.;COPYRIGHT: (C)2010,JPO&INPIT
