浙江纸箱总厂网架平面尺寸为192m×144m,面积24192m~2,是目前浙江省内覆盖面积最大的网架工程。采用柱网24m×24m,空间大、设备布置灵活。屋面采用3m×3m钢筋混凝土带肋板。 该工程整个网架不设伸缩缝,又无对称性,所以分析时需进行整体计算,并考虑柱的共同作用。网架总杆件数21620根,节点数5880个,采用空间网格结构实用微机软件MSTCAD系统在微机上实现了该大型网架的图形处理和分析计算。由于满应
The plane size of Zhejiang Carton General Plant is 192m×144m, and the area is 24192m~2. It is the largest grid project in Zhejiang Province. Column net 24m×24m, large space, flexible equipment layout. The roof uses 3m × 3m reinforced concrete ribbed plates. There is no expansion joint in the entire network of the project, and there is no symmetry. Therefore, the overall calculation needs to be performed during the analysis, and the combined effects of the columns are taken into consideration. The number of total poles of the grid is 21620, and the number of nodes is 5880. The MSTCAD system using the practical software of the space grid structure realizes the graphic processing and analysis of the large grid. Due to full
