Experimental Study on the Damage Classification Method With the Performance Curves of R/C Structures Derived From Recorded Accelerations

Abstract

In order to replace the rapid inspection method on visual observation by the instrumentation, the damage classification with the performance curve derived from the measured accelerations is proposed. There are two damage classification methods, which are for the conventional damage classification method and the method for earthquake insurance. In order to verify the validity of the proposed classification method with sensors, a 3-story full-scale R/C specimen was shaken on the E-Defense to confirm the validity of the proposed method. The result said that the evaluated damage classes according to the three methods agreed well reasonably.

Unbiased rank selection for automatic hysteretic response extraction of RC frame buildings using acceleration recordings for post‐earthquake safety evaluations

“…The first approach described by Kusunoki 24 involved correlating the extent of ductility response to building damage. An example of this is shown in Figure 18A.…”

“…An advantage of this procedure is that only floor masses, acceleration recordings, and recording time‐step are needed. The procedure had been shown to capture the behavior of test specimens and existing multistory buildings well, 19,22–24 and modifications to address cases where sensors were not placed on all floors of a building were proposed 23 …”
