某超限超高层建筑结构抗震设计若干问题研究

Research on Several Problems in Seismic Design of a Super High-rise Building Structure

近年来,随着我国社会经济水平的不断发展,国内许多城市高层建筑数量日益增多,同时体型更加复杂,建筑的抗震设计也显得更加重要和复杂。特别是高层建筑,抗震设计对结构的安全尤为重要。文章以国内某超限高层建筑结构的抗震设计为例,分析了结构的剪力及层间位移角等参数,针对结构出现的薄弱层、软弱层提出了相应的加强措施。同时采用基于性能的抗震设计方法,对其性能目标的确定及具体实现进行了详细分析。

In recent years,with the continuous development of our economy,the number of high-rise buildings in many cities is increasing.While the building shape is more complex,the seismic design of buildings is becoming more important and more complex.Seismic design is particularly important for the safety of the structure,especially for high-rise buildings.Taking the seismic design of a high-rise building in China as an example,this paper analyzes the parameters such as the shear force and the story drift ratio of the structure,and puts forward the corresponding measures to strengthen the weak layers of the structure.Also the performance-based seismic design method has been adopted in the analysis of the building,the determination of the seismic objectives of the structure and methods to achieve these objectives are analyzed in detail.
