摘      要：This paper addresses the problem of designing a feedback stabilizing controller for a class of nonlinear civil engineering structures subject to unknown uncertainties and disturbances. By introducing a simple adaptation law for the upper bounds of the unknown uncertainties and disturbances, a new variable structure feedback strategy is proposed to guarantee the asymptotic stability of the overall system. A numerical example is given to illustrate the effectiveness of the proposed strategy to a base isolated structure subject to seismic excitation.
