Research on Analysis Method and Distributing Principle of the Optimal Prestress in Sunflower-Patterned Cable Dome
Sunflower-patterned cable dome which gets stiffness by prestress tensioning and force self-balance is a kind of cable-strut spatial tensile structure. If distribution of prestress in each layer of the structure is appropriate in construction, its deformation under vertical loads will be uniform. In finite element analysis software ANSYS, principle and method of selecting the optimal prestress distribution of sunflower-patterned cable dome were obtained through applying several different kinds of prestress on each layer of loop cable in calculation model and analyzing its deformation uniformity under full-span load respectively.
