Abstract
In case of base-isolated houses, it is necessary to consider an isolation device with a triggering system to prevent isolators from moving against strong wind. The triggering system which enables smooth transition from a locked isolation system to an unlocked one, should be provided. Three-dimensional shaking table tests were conducted to verify the behaviour of lead-bar triggering system under earthquake loading. The triggering system broke down at the same shear force ratio as that designed. And the transition from the locked isolation system to the unlocked one was smoothly performed.
