深井式地下车库车承板内力分析

Analysis of Internal Force of Vehicle Bearing Plate in Deep Underground Parking Garage

深井式地下车库是解决城市停车问题的有效方法,车承板作为其重要组成部分,需要满足刚度和强度要求。通过有限元分析不同支撑条件以及加载方式下车承板的位移和弯矩,并与理论解对比,表明SHELL63单元在车承板设计时具有良好的适用性,并建议车承板采用三边固支,板厚取0.2m。

Deep underground parking garage is an effective method to solve the parking problem in city, as an important part, vehicle bearing plate needs to meet the requirements of stiffness and strength. By analyzing displacement and bending moment of vehicle bearing plate under different supporting conditions and loading modes through finite element method, and compared with theoretical solution, the result shows SHELL63 element has good applicability in vehicle bearing plate design, and the suggestion of three edges clamped and 0.2 m plate thickness in design are proposed.
