A method is presented for active control of reinforced concrete (R/C) structures against seismic excitations. An important aspect of the method presented is the extension of control process into the inelastic range of deformations. Computer software was developed for dynamic inelastic analysis of reinforced concrete structures, including the effects of control forces, illustrating the significance of active control analytically. This necessitated the formulation of stiffness matrix K as a function of time. Hysteretic behavior is modeled following the rules proposed by Takeda et al.[1]. The effects of instantaneous optimal control algorithms were investigated on structural response. Numerical examples were solved to illustrate the process of active structural control for R/C frame structures. The significance of the arrangement of control forces is presented. The results indicate that seismic response of an R/C structure can be reduced significantly with active control. There is an optimum combination of control forces and lateral displacements that can be established through dynamic analysis prior to application in practice.
