Review of Triangular Cross Section Truss Systems

Abstract

The structural advantages and aesthetics of a triangular cross section truss have long been recognized by structural engineers and architects alike. Until recently however, it has not been considered cost effective to design and build this system over the traditional rectangular or two‐dimensional trusses. But with recent advances in welding techniques, the use of computer analysis methods, and the increased availability of structural tubing for truss members, the triangular cross section truss has seen a wide range of new applications. This article examines the advantages and disadvantages of this type of truss as well as past and present uses of the system for various structural applications.
