Analysis and Optimization of Steel Structure for Mechanical Stereoscopic Garage
In recent years,the annual increase in urban vehicle ownership has led many cities to face the challenge of limited parking spaces,making it difficult to find a parking spot.To alleviate the urban parking problem,this article proposes a tunnel-stacked mechanical three-dimensional garage capable of accommodating both buses and small cars.To ensure that the garage meets practical operational requirements,a finite element analysis model of the steel frame structure was established using ANSYS software.This model was used to study the mechanical properties of the garage under partial and full loading conditions.The analysis revealed that the stress and strain values of the steel structure remained within permissible limits for both loading scenarios.To maintain a safety margin in the design and achieve a lightweight construction,different cross-sectional areas of H-shaped steel were selected and analyzed.After conducting this analysis,appropriate cross-sectional parameters were chosen to optimize the structure of the garage frame.Modal analysis was performed on the garage frame under partial and full loading conditions to verify its stability.The optimized garage exhibited significant improvements in its lightweight design compared to the initial design,resulting in a weight reduction of 23.78％.The findings in this article can provide corresponding reference data for the design and engineering application of mechanical three-dimensional garages.
