| 摘 要： | 以某桥梁工程中的人行道雨棚为研究对象,利用有限元软件ANSYS建立了雨棚结构的整体有限元简化模型,对其同时承受风载和雪载的状态进行了静力学分析,得到了它的整体变形和应力分布结果,并提取其整体结构的轴向力和弯矩,作为分析其柱脚的载荷.在Pro/E中建立了柱脚的三维实体模型并将其导入到Workbench中,利用Workbench对其进行加载分析,得到柱脚的变形和应力分布情况.结果表明该雨棚的整体结构和柱脚设计均满足强度和刚度要求.

| Abstract: | Taking a canopy of one bridge engineering as the research object, the simplified finite element mod- el for analyzing the overall structure of the canopy is established based on ANSYS. The static analysis under wind load and snow load is conducted by the model; and the deformations and stresses are obtained. Mean- while, the axial forces and bending moments of the overall structure are obtained too, which as the load for analyzing the column base. The three-dimensional solid model of the column base is established based on Pro/ E and then be imported to Workbench. The analysis is conducted based on Workbench; and then the deforma- tions and stresses of the column base are obtained. The results show that the stiffness and strength of both the overall structure of the canopy and its column base satisfy the requirements. |
