2012-09-05 - An engineering problem! The aim is to provide a transverse restraint to the top of the tent to reduce wind-induced oscillation. However, the clients desired to keep the sun platform to the east clear of any structure. The solution was to create a tensegrity structure using a tension-only member (alpine sling), anchored to the rock with an SLCD, and a compression-only member, (telescoping hiking pole). Uplift from the wind would cause the hiking pole to fall off of the rock, so the restraints of the compression member were reinforced by post-tensioning the system by telescoping the pole in order to reduce uplift on the compression member. The tent is rigid enough against longitudinal oscillations that no external out-of-plane restraints were necessary.:-)
