THREE-DIMENSIONAL SENSITIVITY ANALYSIS IN ARCH DAM SHAPE OPTIMIZATION

    Graphical Abstract
    • Abstract
  • This paper studies 3-D sensitivity analysis in arch dam shape optimization based on FEM with the Improved Semianalytical Method (ISM). Some analytical formulations related to sensitivity calculation are derived. The correspondent programs have been developed. Examples show that ISM has an advantage in accuracy and stability, and is efficient in arch dam shape optimization based on 3-D FEM.
