EXPERIMENTAL STUDY ON DYNAMIC BEHAVIOR OF PASSIVE CONTROL SYSTEM APPLIED FOR CONVENTIONAL POST-AND-BEAM TWO-STORY WOODEN HOUSE USING SHAKING TABLE

In order to reduce seismic response and damage of wooden houses effectively, a series of so-called shear-link-type passive control systems, which include both velocity- and deformation-dependent dampers were proposed. In this study, a number of shaking table tests of the full-scale two-story wooden frame specimens were carried out. The specimens are composed of conventional post-and-beam with structural plywood, or K-brace and damper for structural element. Performance of specimens is discussed by referring to story drifts, base shear forces, damper deformations and forces, and ratio of story's stiffness. Dynamic properties of the structures such as equivalent periods and damping ratios are also discussed. Test results are compared with the prediction made by calculation of response and limit strength.
