| Abstract: | The eagle strategy is used to optimise a reinforced concrete (RC) ribbed floor system, including floors and underground garage roofs. This study takes the cost as an objective function and satisfies the constrained condition such that an optimal layout is obtained for different column grids. In addition, an optimal section of the beam and slab as well as the corresponding reinforcement are obtained. The RC ribbed floor is optimised according to the Chinese standard, whose two column grids are 8 and 6 m, respectively. The effect of optimisation is determined to be sufficient and applicable to practical engineering. |
