NUMERICAL MODELING OF TRADITIONAL JAPANESE WOODEN STRUCTURES BASED ON FULL-SCALE SHAKING- TABLE TEST RESULTS

摘要

Seismic behaviours on full-scale specimens of wooden frame structures built up by the Japanese traditional constructing way were observed on the shaking-table tests at "E-defence" in Hyogo, Japan in 2011. In this paper, emphasis is put on reproducing numerically frictional and slipping behaviour at un-anchored basements of the traditional wooden frames specimens. Adequate identifying way of structural parameters for numerical simulations is considered to evaluate and predict accurate responses. Through those numerical studies, the following features of the un-anchored structure are assured : 1) Sensitivity for the modeling dispersions appears at the foundations and sliding responses are affected by both dispersions of modeling parameters at the basement and the upper structures, and 2) Extent of sliding responses are correlated to the ratio of shear force strength vs. subjected mass at each built-up column rows.
