Seismic simulation analyses for woodframe houses: Modeling of hysteretic characteristics and the verification with shaking-table test

A method to construct nonlinear characteristics of woodframe houses on basis of hysteretic characteristics of beam-column and braces, which are extracted individually from pseudo dynamic tests is proposed in this paper. A proposed hysteresis model is expressed by combining two types of Bouc-Wen model; one is of spindle-shaped and the other is of strong slip behavior. The applicability of the proposed model is confirmed by a simulation analysis for the results conducted by shaking-table test. It is shown that the computed results with use of the proposed model agree satisfactorily well to the experimental results.
