Abstract
With the rapid development of society, the shortage of land resources, the high-rise building more and more get the favour of developers. So the graduation design, selection of high-rise office building design, structural form with frame - shear wall structure. Main content including the architectural design part, and the structural design part. Building part including the floor plan layout, construction drawing, etc. Structure design part includes: the size of the primary structures, calculation of stiffness characteristic value, SAP2000 modeling calculation of structure vibration mode, the modal decomposition method is used to calculate the elastic displacement under seismic action, seismic action calculating the Angle, wind load and seismic action use D value method to carry on the part of the framework of internal force calculation, according to the equivalent bending stiffness to the internal force distribution, coupling beam of shear wall under the vertical load calculation of internal force, using the bending moment secondary distribution method of internal force calculation, considering various loads of internal force combination, to achieve "strong shear weak bending", "strong column weak beam" shifted control section internal force and reinforcement calculation of structure components and foundation design. Finally PKPM computing and error analysis.
Keywords: high-rise frame - shear wall vibration mode decomposition bending moment secondary distribution
