Structural control through energy dissipation systems has been increasingly implemented internationally in the last years and has proven to be a most promising strategy for earthquake safety of the structures. In extending the “classical” approach of the capacity design for earthquake structural resistance, the integration of passive damping devices within the structure aims at the energy dissipation within specific structural zones. The present paper examines an alternative control system for achieving dynamic structural adaptability. The prototype system developed, consist of an energy dissipation device and a cable bracing mechanism with a kinetic closed circuit, working only in tension. The closed bracing mechanism does not practically affect the initial stiffness of the system, i.e. the concept relies on two completely “separate” systems: a primary for the vertical- and wind loads and a secondary for the earthquake loads. An additional feature of the bracing-damper mechanism compared to conventionally passively controlled systems, is the contribution of all bracing members to the energy dissipation during a loading cycle. Analysis model considerations for describing the physical behavior in computational language of the system are presented, by incorporating the SAAP2000 program, revealing step by step the procedure followed for the resulting desired performance. The investigation among different ways to model the behavior of the elements that compose the dual system concludes with a proposed preliminary design methodology.
