Title: Strut Structure and Rigid Joint Therefor
Published: January 01, 1996
Abstract: A highly rigid structure is provided using six struts connected at three upper and three lower nodes to upper and lower support structures. The joint assemblies are formed by half- spherical balls attached to the ends of each of the struts, and retained within cylindrical apertures, such that the center lines of the struts intersect at the nodes. Bending loads on the struts are thus eliminated, while the design and construction of the structure is substantially simplified.
