【摘要】 为直观形象的描述烟囱在地震作用下的结构破坏机理,提出建立烟囱在地震作用下的可视化仿真系统。该系统以VC++为平台,融合OpenGL图形技术,利用ANSYS软件生成的数据,通过对不同烟囱结构进行参数化建模,实现了在不同工况下烟囱地震动力特征图形三维可视化仿真。实例得出,在水平地震作用下能引起烟囱结构物上部破坏的结论。同时系统还具有查询不同烟囱的结构参数及任意截面在地震作用后的壁厚值的功能,为烟囱抗震设计及预测结构物的震害提供了直观依据。更多还原

【Abstract】 In order to describe the failure mechanism of the chimney under earthquake directly,the visual simulation system of the chimney under seismic action is proposed and established.Taking VC++ for platform,combined with OpenGL graphic library and the data files from ANSYS,and based on the parameterized modeling for different chimneys,the 3D visual simulation which could show the dynamic properties of chimneys subjected to different kinds of seismic action is finished.The example comes to the conclusion that the top of the chimney would be damaged under horizontal seismic action.The system also achieves the strong function for making inquiries about the structural parameters of different chimneys,and the thickness of the chimney at any positions under earthquake action.It provide the direct basis for the seismic design of chimney and prediction of earthquake damages.更多还原
