Multi-Objective Optimization for Shape Design of Arch Dams

Multi-criteria optimization of concrete arch dams

“…Sun and Du took strain energy into account as an objective function which has managed to reduce the strain energy and deformation modules for optimized design [19]. Multi-criteria optimization of arch dam has been studied and the volume of concrete is considered as the rst objective function with principal tensile stress of dam body as another objective function [19][20][21][22][23][24][25]. Importance of tensile strength in unreinforced concrete arch dams makes it as an important parameter to a ect the dam design.…”

“…In an optimization process, optimization of arch dam and other structures could transform a multi-objective problem into a singleobjective optimization problem which is called classical multi-objective optimization method or decomposition method. In this method, an optimization problem with m-objective can be rewritten as an M-factor term, in which the coe cients of each of the objectives show the importance of that objective function for decisionmakers, and sum of coe cients should be equal to one [19][20][21][22][23][24][25][26].…”

“…Multi-objective optimization of concrete arch dams has been the subject of many studies for the last decade [19][20][21][22][23][24][25]. Wen-jun et al used the fuzzy theory to deduce both dam volume and maximum tensile stress as objective functions [20].…”

Shape Optimization Design of Gravity Buttress of Arch Dam Based on Asynchronous Particle Swarm Optimization Method

“…More and more designs of arch dam in China have to be faced with complicated and unfavorable topographic and geologic conditions, and setting gravity buttresses is a common way to solve this problem [1]. At present, the structure optimization design method has been widely used in the shape design of arch dam [2]. However, the optimization design method was rarely used to design the gravity buttress of arch dam in the past.…”

Shape optimal design of materially nonlinear arch dams including dam-water-foundation rock interaction using an improved PSO algorithm

“…During the last years some progress has been made in optimum design of arch dams under static and dynamic loads where arch dam-water-foundation rock interaction has been neglected and conventional mathematical models have been utilized for analysis approximation and optimization task (Wasserman 1983;Yao and Choi 1989;Zhu et al 1992). In recent years, the studies on the subject of arch dam optimization are being developed (Sun et al 2007;Zhang et al 2009;Li et al 2009). A study has also been introduced by the authors ) so that shape optimal design of arch dams including hydrodynamic effects is achieved using a fuzzy inference system and wavelet radial basis function neural network.…”
