　　Characteristics of tension structures
　　Tension structures are ones in which the main load-carrying members transit applied loads to the supporting structures by direct stress without flexure or compression. Their cross-sectional dimensions and methods of fabrication are such that their shear and flexural rigidities, as well as their buckling resistance, are negligible. There are two broad classes of tension structures: cable structures, comprised of uniaxially stressed members, and membrane structures, comprised of biaxially stressed members.
