Abstract In order to realize lightweight design of the circular stacker\|reclaimer main girder, the ESO(evolutionary structural optimization) method was used to study the topological optimization of the fetching material main girder web, and based on stresses ESO was achieved by secondary development of ANSYS using the APDL(ANSYS parametric design language ). Moreover, a sensitivity redistribution method in combination with the above method was also used to control checkerboard patterns so as to have a smooth transition of each element's contribution or impact factor to the whole structural performances. Finally, a clear result is obtained, offering an reference model for the next design and optimization of the fetching material main girder．
