三角形截面的空间格构式刚架体系静力参数分析

Static Parametric Analysis of Portal Frames With Spatial Latticed Triangle Section

截面为三角形的空间刚架是一种新型空间管结构,具有优美的造型和优良的经济性。本文探讨了这种结构的受力特点, 通过正交设计,找到了对用钢量有显著影响的主要结构参数并研究了各参数的合理范围,并将该结构与实腹式变截面刚 架及网架结构的用钢量进行了对比分析。

As a new structural type, the portal frame with spatial latticed triangle section made itself promising by its elegant shape and prominent economical characteristics. This paper studies the structure's characteristics under loading and the reasonable ranges of some critical structural parameters, and make an economic comparison with light-gauge steel gabled frames and grid structures.
