713.20 Compression Members
713.21 Behavior of Compression Members in Spherical Tensegrity Structures: In spherical tensegrity constructions, whenever a tension line interacts with a compression strut, the line does not yield in a circumferential direction away from the strut. The islanded compression member, combining its two ends’ oppositely outward thrust, pulls on the omni-integrated tension network only acting as a radially outward force in respect to the sphere’s center.
713.22 When we remove a compression member from a tensegrity sphere of more than three struts, the compression member of the original triangular group, when released on one end, does not shove by the tension member to which it was fastened. It is not fastened in shove or sheer. It pulls outwardly of the spherical system, away from the tension members at both of its ends simultaneously; when released, it pops only outwardly from the sphere’s center.
713.23 When inserting a strut into a tensegrity sphere, you are pulling the tensional network only outwardly of the system in order to allow the strut to get into the system, that is, toward the structure’s center. The strut pulls only outward on the two adjacent tension members to which it is fixed, trying to escape only radially outwardly from the system’s center.
