本文进行了较多数量大比例型钢混凝土柱温度场试验,研究了升降温作用下型钢混凝土柱试件的温度场分布规律。在试验研究的基础上,提出了升降温火灾作用下型钢混凝土柱温度场的理论计算模型,理论计算结果与试验结果吻合较好。本文计算模型为型钢混凝土柱温度场分析提供了可靠方法。
In this paper, a large number of large-scale steel column temperature field experiments were carried out to study the distribution law of the temperature field of SRC columns under the condition of increasing and decreasing temperature. Based on the experimental study, the theoretical calculation model of the temperature field of steel reinforced concrete column under the action of temperature rise and temperature is put forward. The theoretical calculation results are in good agreement with the experimental results. The calculation model in this paper provides a reliable method for the temperature field analysis of SRC columns.
