Abstract：This paper deduces the calculation formula of the nominal lateral drift and the harmful interlayer drift of the isolation structure by using the isolation cantilever Timoshenko beam model with the horizontal load of the matrix distribution. The distribution law of the harmful and the nominal lateral interlayer displacement about a shear wall structure of high-rise isolation is studied, the and optimal control design of the isolation structure is carried out with nominal lateral drift and harmful interlayer drift and the economic indicators of the two design schemes are compared. In addition, some useful conclusions are obtained by comparing the damage ruels of the upper structure of the two design schemes with the nonlinear time history analysis of the large earthquake. And this study can provide support for the further study of isolated structure.
