| 摘 要： | 本文采用有限元法对钢筋混凝土板建立三维分层模型和三维分离模型并进行计算,将实验结果与常温下的三维分层模型以及分离模型的计算结果进行了对比;同时对比了相同条件下常温与高温混凝土板变形情况,以及高温下两种模型的变形.得出：工程应用中,在误差允许的范围内,优先考虑用分层模型来模拟钢筋混凝土板和温度载荷对钢筋混凝土板变形有很大影响的结论,从而为进一步进行钢结构的整体分析提供了依据.

| Abstract: | The paper builds and calculates the three-dimensional layer model and three-dimensional separate model for the reinforced concrete slab with the finite element method, compares the results of the experiment, the three-dimensional layer model and the threedimensional separate model built with solid element, then compare the deformations of the concrete slab at environment temperature and high temperature. At last the paper compares the defonuations of the two three-dimension models at high temperature. The conclusion is got that it is better to use layered model to model the reinforced concrete slab in the error permitted scope, and that the temperature is an important factor to affect the deformation of the concrete slab. That provides the foundation for the analysis of the whole steel frame. |
