【Abstract】 With the renewal of numerical analysis technique, the structural topology optimization technique has been applied in the architectural field. This paper explores the structural configuration of a large-scale steel skylight for a sales center by using the continuum topology method. The paper uses the finite element analysis software ANSYS Workbench to build a model, adopts SIMP method for analysis and calculation to identify the optimal load transfer paths, and then develops a preliminary structural layout. Additionally, static and stability analyses are performed on the structure by using the finite element software MIDAS GEN. The feasibility and safety of the long-span skylight structure are verified following the validation of the structural topology, and all calculated analysis parameters meet the requirements of relevant codes and standards. The continuum topology optimization method adopted in this paper provides valuable reference for the design of similar structures in the future.更多还原
