| Abstract: | Introduces the efficient computer aided design method to optimize the section of steel-concrete composite beams by combining FEM structure analysis with optimization algorithm and an efficient shearing force link model of steel-concrete composite beams.The authors establishe the finite element analysis model,optimization parameter model,optimization mathematics model of steel-concrete composite beams and programs analysis file and optimization control file by using the ANSYS parameter design language.The optimum of the steel-concrete composite beams section is obtained after computing and the optimization result indicates that the method is efficient to optimize the section of steel-concrete composite beams.So it could be applied extensively in the engineering of the steel-concrete composite beams section optimization design. |
