フレームモデルによる２層木質制振架構の地震応答解析

Abstract

This paper proposes an accurate, member-by-member analytical model for two-story timber structures having energy dissipation walls and/or plywood shear walls. Various member joints are modeled by using nonlinear spring elements whose properties derived from numerous test results. The analyses were found to reproduce both local and global responses obtained from shaking table tests of a variety of two-story timber frames. Moreover, unsteady behavior of slip-hysteretic structure, energy absorption performance and deformation state of energy dissipation wall arranged in 2nd floor are discussed.
