Abstract
The present invention relates to a suspended large steel frame support structure with an additional damping device, which is applicable for high buildings and composed of a main structure and a sub-structure. The main structure is adopted with a large steel frame support structure, which is characterized that the support structure is composed of a splayed tough support and a reversal splayed pre-stress cable; the sub-structure is suspended on a large beam of the main structure; a horizontal damping device is arranged between the sub-structure and the main structure. The reversal splayed pre-stress cable can offset large push generated by the splayed tough support and transmit load in the large beam span to a large column in the form of pull to reduce the shearing force, the bending moment and the deflection of the beam, therefore, compared with a large frame structure, the large steel frame support structure can improve lateral resistance; compared with a large truss structure, the large steel frame support structure relieves collective stress. A damping device provided between the main structure and the sub-structure consumes more horizontal momentum, and greatly reduces the displacement and the acceleration of suspended floors.
