Reinforced concrete floor is widely used as one of the main components of the projectstructure. With the improvement of people’s living level, the use of Radiant Floor Heating ismore and more widely, especially in the north of China. Because of its unique cooling mode,Radiant Floor Heating technology has a certain effect on frame beam, plate and column. Thestructure design of many buildings is in accordance with the form of heating radiators,however, it’s always changed into the Radiant Floor Heating system in the process of using.This has some influence on building durability and safety. In addition, cut corners often occurin floor heating construction. Consequently, Researching the structure temperature stressunder Radiant Floor Heating effects are particularly important, and this also provides amethod for the study of the structure temperature stress analysis.For the above problem, it combines the research status of reinforced concrete slab in thispaper, and a simple introduction is given about the theory of finite element analysis oftemperature stress, the causes of reinforced concrete structure temperature stress are discussed,based on the finite element theory, the calculation model of reinforced concrete floor slab isestablished, using finite element analysis software ANSYS, action effects of floor slabs underRadiant Floor Heating effects were analyzed. The main research contents are as follows:(1)The model of reinforced concrete slabs is established on the absence of Radiant FloorHeating using the finite element analysis software ANSYS, and the stress of floor slabs isanalyzed in its own weight of floor slab, the analysis results are basically consistent withtheoretical calculation results, and the foundation is set up for the further analysis.(2)The action effects of reinforced concrete floor slab is researched under the influenceof the Radiant Floor Heating temperatures, The results shows that, compared with the floorslab of non-temperature load, the compressive stress is increasing in the top of floor slab, butthe tensile stress in bottom of floor load is getting smaller, and the crack appear in all aroundof the floor slab when the temperature difference increase.(3)The action effects of reinforced concrete floor slab is researched under the influenceof different thicknesses of Radiant Floor Heating in this paper. The results shows that thedeflection of floor slab is increasing, and the maximum tensile stress and the maximumcompressive stress also increase followed by it. But the influence is small, and it can beaccepted by the reinforced concrete floor slab.
