The simulated analysis of temperature stress produced by hydration heat generated in the concrete structure

基于水化热产生温度应力的基本特性,利用有限元分析软件ANSYS计算出水化热在混凝土结构中产生的温度数值,并就SPF动物房建筑部分超长混凝土框架梁(83.1m)在水化热产生温度的情况下,对结构构件中产生的温度应力和应变进行仿真分析,根据分析结果总结出水化热产生不利影响的防治措施,为工程结构设计,施工以及后续的工程水化热研究工作提供理论依据和数据支撑。

In this thesis,we make use of ANSYS to calculate the temperature value produced by hydration heat of concrete structure based on the features of the temperature stress,what is more,carrying out simulated analysis on temperature stress and strain produced by hydration heat of the ultra-long beam（83.1m） contained by SPF animal room building,then concluding the methods that can deal with the problems made by heat hydration.All of the achievements can provide principle and data resources for the engineering structural designing,constructing and following hydration heat study.
