某高层办公楼结构抗震设计

With the rapid development of science of anti-seismic and damping，people's demands to improve the seismic resistance are increasing.seismic design of buildings has become a critical issue in the construction industry. this paper is made to analysis an high-rise office building in Wuhan for structural seismic design, including load calculations, structural internal force calculation, parameters selection, the construction and simplification of structure model, and the structure's specific design. In this paper, the analysis and design methods is equivalent base shear method, through the calculation, this paper get the natural vibration period and relative storey displacement of the building under horizontal earthquakes, and conduct specific seismic design based on this and the existing earthquake resistant code of buildings.
