An Application of Simulated Annealing to the Optimum Design of Reinforced Concrete Retaining Structures

Abstract

This paper reports on the application of a simulated annealing algorithm to the minimum cost design of reinforced concrete retaining structures. Cantilever retaining walls are investigated, being representative of reinforced concrete retaining structures that are required to resist a combination of earth and hydrostatic loading. To solve such a constrained optimisation problem, a modified simulated annealing algorithm is proposed that avoids the simple rejection of infeasible solutions and improves convergence to a minimum cost. The algorithm was implemented using an object-orientated visual programming language, offering facilities for continual monitoring, assessing and changing of the simulated annealing control parameters. Results show that the simulated annealing can be successfully applied to the minimum cost design of reinforced concrete retaining walls, overcoming the difficulties associated with the practical and realistic assessment of the structural costs and their complex inter-relationship with the imposed constraints on the solution space.

Multiobjective Optimization of Concrete Frames by Simulated Annealing

“…Kicinger et al (2005b) recently reviewed evolutionary algorithms applied to structural design. The use of nonevolutionary algorithms is scarce, exceptions being, for instance, in the research of Balling and Yao (1997) and Ceranic et al (2001). Recently, our research group has also used nonevolutionary algorithms to optimize earth retaining walls, portal and box road frames, building framed structures, road vaults, and bridge piers (Gonzalez‐Vidosa et al, 2005; Perea et al, 2006a, 2006b, 2008; Paya et al, 2006a, 2006b; Carbonell et al, 2007; Yepes et al, 2008).…”

“…Several cooling schemes have been presented in literature such as linear, logarithmic, geometric, and Lundy and Mees that are represented by Eqs. (15)(16)(17)(18), respectively [21,[30][31][32].…”
