IDENTIFICATION OF SWAY ROCKING SPRINGS AND PILE DAMAGE DETECTION USING SUBSPACE METHOD

Structural health monitoring is attracting attention as an effective means to understand the functional continuity of a building after earthquake. Previous studies have reported that continuous use buildings was restricted damage their foundation structures despite minor themselves. We propose identify soil springs using subspace method one indirect methods; then, this approach verified via numerical analysis sway rocking model. Furthermore, proposed applied measured data from large shaking table test pile detect piles.
