Optimization of Shell Structure Using Genetic Algorithm

Dr. R. J. Fernandes, Sushmita Yadahalli

Abstract: Shell structures are used efficiently and also economically in many fields of architecture and engineering. Shell roofs are made from structural ?skins? where the shell material is thin in section relative to the other dimensions of the roof and undergoes relatively little deformation under load. They are commonly used where a building interior needs to be free from intermediate walls or columns that might support a more conventional flat or pitched roof. Shells provide an aesthetic view. In this paper, optimization is carried out for different grades of concrete keeping thickness, chord length, and semi-central angle variable, whereas in a shell roof with an edge beam width of the beam is constant and the depth of the beam varies. A computer program is written in MATLAB software for the optimization process using the genetic algorithm method, and analysis results are retrieved from SAP2000 software to carry out the optimization process.

Keywords: shell structure, genetic algorithm, shell roof, edge beam, concrete
