MECHANICAL THREE-DIMENSIONAL PARKING STRUCTURE DESIGN AND ENGINEERING PRACTICE
Because of the limitation of the site space,the mechanical three-dimensional parking garage adopts a single-span frame structure.Under the action of horizontal force(wind and earthquake,but the main control is wind load),the zero-stress area of the basement is very large,there is a risk of tipping over.The short-side deformation of single-span structure is large,so it is necessary to take wind-resistant measures to limit the displacement under wind load.Based on the structural design of mechanical three-dimensional garages in Shenzhen,and based on the structural characteristics of the project,multiple structural calculation software were used for comparative analysis.It was found that only the use of anti uplift pile foundations can meet the actual stress requirements and effectively solve the problem of overall structural overturning.At the same time,the use of outsourced column footings can also improve the overall stability of the structure.
