Development of Passively Controlled Small Wooden Structures and the Design Method

Abstract eng:
In this paper, application of passive control devices to small wooden structures is introduced. Chapter 2 discusses the seismic behavior and the performance of structural components of conventional post and beam wooden structures especially focusing on behavior of connections. They are modeled by combination of inelastic axial, shear and rotational spring based on results of fundamental material and fasteners tests. Chapter 3 introduces the experiments and analyses for the structural behavior of the energy dissipation walls which involve unique mechanics to dissipate most energy in the dampers. In Chapter 4, the seismic behavior of passively controlled wooden structures is investigated through both experimental test and numerical analysis. Detailed framing analysis models for energy dissipation wall and plywood sheathing wall are also introduced. Furthermore, a design methodology for passively controlled wooden houses is proposed in Chapter 5. The accuracy of the results by the proposed method is confirmed through time history analyses.
