摘要
Abstract
The thermal stress simulation analysis is the foundation of the temperature control design, and it has important effect on the construction and safety of the project. The thermal stress in concrete structure is influenced by many factors. It selected linear expansion coefficient, elastic modulus, temperature increments and creep rate as 4 main parameters with characteristic of interval distribution. Combining with interval theory and finite element method, the calculation formula for the interval of thermal stress with variation of parameters was deduced based on a comprehensive analysis of the impact of concrete temperature and established calculation method for the thermal stress of concrete structure under the influence of uncertain factors.关键词
