DEVELOPMENT OF DAMPER FOR VIBRATION CONTROL OF DETACHED HOUSES

摘要

By using a damper at the relation story for detached houses, the damping effects for compression side decrease. The reason is that the compressive force is dissipated by deformation, for example, by bending in case of using a brace. So that, the damper was developed that exercise efforts in the tensile direction only, with automatic stroke return. By using this damper, the design for the brace become easier because the action of the tensile force is the only consideration. The damper uses Binghum Material with the unique physical property. It allows the energy dissipation and the self restoration to operate as one without a complex mechanism. The real scaled damper was designed applicable to detached houses. It has rated reaction force of 20kN and maximum stroke of 50mm. And the loading test was performed two patterns. One was only the damper in the static and the dynamic condition, another was steel frame with the damper. The results showed that this damper has made possible easier design for the brace, construction and the highly effective for the vibration control of detached houses.
