説明

Passive control schemes to mitigate seismic damage of wood houses are discussed. Extensive shaking table tests are conducted for various full-size wood-frame specimens. This paper focuses on the specimens with velocity-dependent dampers, and compares their dynamic properties and performance with those of conventional wood frame as well as passively controlled frame utilizing deformation-dependent dampers. Dynamic properties are defined by equivalent periods and damping ratios. Performance is assessed by referring to story drifts, accelerations, base shear forces, damper deformations and forces, and connection deformations. Test results are also predicted by proposed simplified rules based on the dynamic properties and response spectra.
