Abstract:
A testing system for a structure comprising:a shaking table mounted on a foundation by way of a first actuator; a simulated structure having at least one second actuator fixedly mounted on the foundation and separately from the shaking table; a reaction force measuring device to measure a reaction force generated by a test piece structure connected to the simulated structure; a digital computer which stores a numerical model that is virtually connected to the test piece structure; a controller to control the simulated structure; and a shaking table motion measuring device to measure motion of the shaking table, wherein the digital computer includes time control means to control a shaking timing of the shaking table and means for storing a shaking wave form of the shaking table, and the digital computer outputs a control signal to the controller based on the output of the reaction force measuring device.
