【提要】  中關(guān)村軟件園光盤結(jié)構(gòu)由四根懸臂柱懸吊巨型雙層鋼結(jié)構(gòu)盤面組成。采用ANSYS有限元計算軟件，分析了88種不同荷載組合下結(jié)構(gòu)的主要受力和變形特性，結(jié)構(gòu)的靜力計算結(jié)果表明，結(jié)構(gòu)各構(gòu)件的受力和變形均滿足設(shè)計控制目標要求。通過動力分析可以發(fā)現(xiàn)，結(jié)構(gòu)的第一
振型為豎向振動，動力分析結(jié)果也滿足抗震要求，說明結(jié)構(gòu)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.
