The Analysis Of Temperature Stress In Overlong Concrete Structure And Finite Element Analysis

The national economy in the rapid development, people on the constructionsafety and aesthetics have a new understanding and new requirements, some publicbuildings are gradually to the comfortable, large-scale development, the over longconcrete structure come now, large public buildings and industrial buildings.For theintegrity and the beauty of the consideration, our designers usually have no or in thesebuildings less expansion joint, however for the super long structure, temperaturestress is an important factor to be considered, is also the main cause of cracks in thesestructures, analysis of the temperature stress of super length concrete structure and hasimportant significance is simulated with finite element software.The main contents are as follows: firstly outlines the research background anddevelopment situation of super long concrete structure, the over long concretestructure shrinkage creep theory and related theory, the temperature stress theory.Then briefly introduced the application of field monitoring technology in ultra longconcrete structure, on a real super long concrete structure was the site more than ayear of tracking and monitoring, and the monitoring data analysis. The effect of superlong concrete structure in the overall actual temperature were simulated and analyzed,concluded that the temperature stress of super long concrete structure distribution, theparameter analysis of factors and effects of stress on temperature.Based on the temperature stress of super long concrete structure monitoringanalysis and Ansys finite element simulation analysis and draw some usefulconclusions are drawn, which is of great help to the design and construction of thesimilar super long concrete structure.
