OPTIMIZATION DESIGN OF RETAINING WALLS USING MODIFIED SIMULATED ANNEALING ALGORITHM

Abstract

In this paper, a procedure is developed for designing low-weight cantilever reinforced concrete retaining walls, using modified simulated annealing algorithm (MSAA). The objective of the optimization is to minimize the total weight per unit length of the retaining structure based on the ACI 318-05 procedure. The algorithm is validated using two benchmark case studies with continuous variables for wall geometry and discrete variables for steel reinforcement to optimize the structural design. Finally, the numerical results demonstrate the efficiency of the presented algorithm for this class of problems.

Keywords: Optimization; retaining walls; modified simulated annealing algorithm.
