- Abstract
With the isolation system based on pure rolling as the object of study, the computer program was develeped to calculate its seismic displacement based on its characteristics. And then, experiment method and theory analysis method were adopted to analyze the new computer program and the traditional calculation method’s rationality in contrast. It is shown that the computer program is reasonable, and its results are relatively accurate and conservative. The traditional calculation method based on the rigid-plastic relation of force and displacement is illogical, and its results are relatively small. When subjected to earthquakes, the structures maximum relative displacement would be larger than the earths maximum absolute displacement.
