利用通用有限元分析软件ANSYS,建立了某混凝土结构电力设备实验室的整体实体模型。结合软件的参数化编程技术(APDL),以项目建设所在场地的实测单日气象信息为依据,分析了从日出到日落全过程中,太阳辐射条件下结构的温度场和应力场变化情况,为该实验室的设计提供指导。分析结果表明:该罐体实验室采用混凝土结构体系是可行的;太阳辐射造成的温度应力不仅可能造成表层混凝土的开裂,还可能危及结构安全。因此在该类型结构设计中,应考虑由于太阳辐射造成的温度应力。
Using the general finite element analysis software ANSYS, the overall solid model of a concrete structure power equipment laboratory was established. Based on the measured single-day meteorological information of the site where the project is located, the temperature and stress field of the structure under the solar radiation from sunrise to sunset are analyzed combining with the software parameterized programming (APDL) Provide guidance for the design of the laboratory. The analysis results show that it is feasible to adopt the concrete structure system in the tank laboratory. The thermal stress caused by solar radiation not only may cause cracking of the surface concrete, but also may endanger the safety of the structure. Therefore, in this type of structural design, the temperature stress due to solar radiation should be considered.
