Abstract

A typical stayed column consists of a slender core supported by three stay frames which are equally spaced around it. This paper considers the effect of varying a type of stayed column which was first analysed, designed and tested for NASA by Hedgepeth and which was then refined by Williams et al. Each of the three stay frames originally had a central cylindrical spoke carrying the compression induced by pretensioned stays which radiate from its end to the hollow cylindrical core. The theoretical studies presented show that replacing the cylindrical core and spokes by different cross-sections can give columns that are substantially lighter and/or more compact. Four types of cores with differing advantages are considered and the paper also examines the possibility of balancing between mass and volume to minimise whichever is critical for a particular Space Shuttle mission.
