关于斜交网格结构最优节点高度的研究

Discussion on the Optimal Node Height of Skewed Grid Structure

为找出最优节点高度及其影响因素,利用力学基本知识,重新计算了W. F. Bake的轴力和最优节点高度,指出轴力错误的原因,以及最优节点位于高度的3/4处。通过在Ansys编写循环语句找出侧移最小的节点位置,绘制了最优节点高度与框架的外柱倾斜度、高宽比、梁柱刚度比的关系曲线,以期为以后的设计提供参考。

In order to find the optimal node height and its influencing factors,the basic knowledge of mechanics is used to recalculate the axial force and the optimal node height of Banker The reason for the axial force error is pointed out,and the optimal node is located at the height of 3/4.By writing a loop statement in Ansys to find the position of the node with the smallest side shift,the relationship between the optimal node height and the outer column inclination,aspect ratio,and beam-to-column stiffness ratio of the frame is drawn,in order to provide reference for future design.
