Sažetak
A new methodology for seismic control design of MDOF structures is put forward.The methodology is developed for shear-type building frames with supplemental system of braces with dampers. Hysteretic dampers are modelled to be elasto-perfectly plastic. The mechanical parameters of the damper, the supplemental system (damper + brace) and the controlled structure are first defined. Next, based on modal analysis method, the controlled MDOF structure is converted to the equivalent SDOF structure, and the distribution of elastic stiffness of damper on the MDOF structure is derived. Then, a procedure is compiled to achieve the elastic stiffness, the yielding drift and the ductility factor of the damper on each story of the MDOF structure. Finally, the procedure is used for seismic control design of three example structures. Time history analyses show that the proposed methodology is feasible.
