Abstract:

Article Preview

For the displacement-constraint device with hysteric-friction isolation system, the judgment condition of soft-collision between the isolation layer and displacement-constraint device is put forward, the motion equation of the isolation system in consideration of friction and soft-collision is established, the nonlinear analysis program is worked out, and several kinds of inflection points in the program are given and the corresponding processing method of the inflection points is introduced. The nonlinear response analysis of the isolation system results indicate the displacement-restraint device can ensure the upper structure safety; also can decrease the displacement of the isolated layer.
