【提要】  中关村软件园光盘结构由四根悬臂柱悬吊巨型双层钢结构盘面组成。采用ANSYS有限元计算软件，分析了88种不同荷载组合下结构的主要受力和变形特性，结构的静力计算结果表明，结构各构件的受力和变形均满足设计控制目标要求。通过动力分析可以发现，结构的第一
振型为竖向振动，动力分析结果也满足抗震要求，说明结构形式是合理可行的。

Abstract:The disk canopy structure in Zhongguancun software plaza is composed of a huge double steel disk canopy structure suspended by four cantalever columns.The software ANSYS is used to calculate the bearing and deformation characters of the structure under 88 load combinations.The static calculation results show that the itnernal force and deformation of the members meet the design requirement.It is found that the first vibration mode is vertical by the dynamic analysis and the structural response are in the allowable range of the code,which shows that the structure system is reasonable.
