Study on the Seismic Performance of the Braced Controlled Rocking Reinforced Concrete Frame Structure System
On the basis of structural concept design, this paper puts forward a new braced controlled rocking reinforced concrete frame structure system, researching dynamic characteristics of the BCR-RCF structure when the joints is been weakened in different levels by using finite element analysis software Abaqus, analyzing the reasonable degree of rocking joints stiffness weakening. By comparing the dynamic response of conventional reinforced concrete frame and the BCR-RCF structure, it shows that the BCR-RCF structure can effectively reduce the structural shearing force and acceleration response, however, displacement and velocity response is bigger than RCF structure. Compared with the RCF structure, shearing force and displacement responses of the BCR-RCF are more evenly distributed along the floor, which helps preventing excessive concentration of interlaminar deformation, so that materials of every layer can be fully utilized. After adding metal damper into the BCR-RCF structure, the displacement response can be effectively controlled.
