An approach to optimizing a cylindrical rod roof
Incoming article date: 30.06.2022As part of the optimization of the design solution, studies of a cylindrical rod roof with increased rigidity of the support ribs and taking into account the reinforcement of the system with puffs were carried out. The required distance between the tension elements along the length of the structure is determined and the dimensions and shape of the section of the lower ribs are proposed. An optimality criterion with control parameters has been developed and three standard sizes of rods for the greatest efforts have been taken into account. Internal force factors and node movements with and without reinforcement are obtained. A positive redistribution of efforts on the surface and a decrease in the deformability of the roof were revealed. The dependence of the main geometric parameters on the mass is established.
