摘要
局部双层柱面网壳可以通过后张拉闭合平板网架中预留缝隙的方法张拉而成。提出一种可用于张拉成型局部双层柱面网壳的平板理论模型,给出预测成型形状的理论公式。利用ANSYS 10.0有限元计算程序,通过不同节点连接方式模型的对比分析给出最适合张拉的理想模型。
By means of post-tensioning, the flat space truss can be formed into a local double-layer barrel-vault reticulated shell when the original gap is turned off in the flat space truss. It is proposed a flat space truss theoretical model which can form a local double-layer barrel-vault reticulated shell and the theoretical formulas are given for predicting the forming shape. Using ANSYS 10.0 the finite element program, an ideal model is obtained through comparative analysis of several different node connection models.
