Abstract EN
A technique for simultaneous topology, shape, and sizing optimization of tall guyed masts is presented in this paper.
The typical scheme of telecommunication masts that are triangular in plan and supported by a certain number of guys’ levels is examined.
The objective function is the total mass of the mast, including the mass of the guys.
The mast structure is optimized for self-weight and wind loading that is evaluated according to Eurocodes.
The nonlinear behaviour of the guyed mast is simplified idealizing the nonlinear guys as approximate boundary conditions for the mast.
A comparison of the simplified solution with the results of nonlinear analysis with Ansys shows small discrepancies that are on the safe side.
The constraints involve all strength, local and global stability, and slenderness requirements.
The optimization problem is solved using evolutionary algorithm with original genome repair procedure.
As an example, a typical 96 m guyed broadcasting antenna for mobile-phone networks was designed employing the proposed optimization technique and taking up to 10 guys’ levels.
It is shown that the optimal mast is supported by 3–5 guys’ levels.
The optimal ranges of all remaining design variables were also obtained.
