摘要
介绍一种截面为三角形的新型空间格构式刚架体系。由于其突出屋面的上弦杆无支撑相连 ,该体系的平面外整体稳定方面的研究就成为一个刻不容缓的问题。通过大量的计算机分析 ,对这种结构体系的平面外整体稳定承载力影响参数进行了研究 。
A new kind of light gauge spatial latticed frame of triangular section is introduced Because of the top chord protruding over the roof without any bracing,it is necessary to make some research on the out plane whole stability of this structure Based on large quantities of computer analysis,the influential parameters on the stability behavior of this structure are studied,some useful conclusions are also obtained
