大跨度厂房自稳定屋架分析与计算

Analysis and calculation of self-stabilizing roofs for long-span plants

采用两跨自稳定立体桁架屋架,综合运用有限元分析与设计软件SAP2000,ANSYS和NIDA软件进行了构件大小及几何尺寸的确定,对结构进行了弹塑性全过程分析及直接分析法分析,并在施工过程中进行了变形监控,产生的挠度与计算值基本符合。

This project adopts two-span self-stabilizing three-dimensional truss roof frame and applies finite element analysis and design software SAP2000,ANSYS and NIDA software were used to determine the size and geometry of the components,and the structure was subjected to a full elasto-plastic process.Analysis and direct analysis method.The deformation was monitored during the construction process,and the resulting deflections were basically in line with the calculated values.
