AP1000核工程中的墙体模块采用的是钢板-混凝土组合结构。安装核电设备要求墙体钢板变形不超过3 mm,试验研究了分层浇筑自密实混凝土对钢板的侧压力与浇筑高度的关系,在此基础上应用Abaqus有限元分析软件对墙体模块中的钢板及其连接杆件的应力和位移等进行了模拟分析,研究了钢板厚度、角钢加劲肋间距以及槽钢拉结杆间距对结构模块变形的影响,为结构模块墙体的优化设计提出建议,并为其后续施工提供参考。
AP1000 nuclear engineering in the wall module is used steel-concrete composite structure. The installation of nuclear power equipment requires that the deformation of the wall steel plate does not exceed 3 mm. The relationship between the lateral pressure of the steel plate and the pouring height of the layered concrete self-compacting concrete is studied. Abaqus finite element analysis software is used to analyze the steel plate And the stress and displacement of the connecting rod are simulated and analyzed. The effects of the thickness of the steel plate, the spacing of the angle steel stiffeners and the spacing of the tie bars on the deformation of the structural module are studied, and suggestions are put forward for the optimal design of the structural module wall Provide reference for its follow-up construction.
