以武汉地铁某三层地下车站为例,采用抗震计算方法反应位移法进行抗震计算分析,介绍反应位移法基本原理,并详细阐述反应位移法所需的各参数和计算过程。通过对此车站的抗震计算分析,表明在6度抗震设防烈度下,结构按照正常使用状况配筋就能够满足抗震设防的要求,抗震工况对构件截面尺寸及配筋不起控制作用,此研究成果可应用于武汉地区地下车站结构的抗震设计中。
Taking a three-story underground station in Wuhan Subway as an example, seismic calculation method is applied to calculate seismic response analysis. The basic principle of reaction displacement method is introduced. The parameters and calculation process of reaction displacement method are elaborated. Through the calculation and analysis of the anti-seismic of the station, it is shown that under the seismic intensity of 6 degrees, the structure can meet the requirement of anti-seismic fortification according to the normal use condition of reinforcement, and the anti-seismic condition can not control the section size and reinforcement of the component. The results can be applied to the seismic design of the underground station structure in Wuhan.
