齐平式端板连接组合节点温度场分布研究

Research of temperature distribution for flush end-plate composite joints

通过有限元方法分析了平端板组合节点连接在升温过程中的温度场分布情况,总结了端板组合节点在高温下温度分布特性,并且结合理论方法给出了此类组合节点温度场实用计算公式,为组合节点抗火性能研究奠定基础。

In this paper, the temperature distribution in elevated temperature of flush end- plate composite joints has been presented by the finite element analysis. Conclusions were given for the characteristics of composite joints with different styles of concrete slab. Some formulas for calculating the temperature distribution of composite joints were also presented in this paper. These works above give a good support for further works on the research of failure mechanism for composite connections in high temperature.
