The Investigation Of The Aseismatic Capability Of The High-Rise Building With Stell Truss Transfer Story Structure

Since the flourishing development of the high-rise building, as modern high-rise building on the functional requirements of large space often need a conversion structure. In the current study of the conversion form by the engineering sector, truss transfer story have a clear stress, the structural forces and lateral rigidity of the truss transfer story is smaller than the beam transfer story, truss transfer story is conducive to lighting and ventilation equipment, and other major pipeline system layout, could take full advantage of the conversion of the building space and achieve outstanding artistic effect and construction features in the construction of the buliding.Therefore, on the basis of the analysis of domestic and foreign scholars, this article did further rsearch of the mechanical properties and elastic earthquake response of the high-rise buliding with truss transfer story under earthquake.First of all, this paper has introduced the basic concepts and design principles of steel truss transfer story building structure, then the mechanical properties of single layer and overlap layer has been analysed;Secondly, this paper has introduced the general theory of the elastic dynamic analysis of the buliding structure with transfer story, in the background of a practical project, used the finite element software-SAP2000, established the three-dimensional finite element analysis model of the original structure, through the response spectrum analysis and the time-procedure analysis, researched the dynamic characteristics of the buliding structure with transfer story, and its lateral deformation and total shear such as performance under the earthquake, analysed its earthquake response under the multi-earthquake;Then analysed the dynamic characteristics and seismic performance of the buliding structure with transfer story. The differences of the cycle and vibration mode, the displacement and layer drift and inter-layer drift angle, the shear and layer shear and other aspects of the performance of the steel truss transfer story structure of different altitude are compared.
