本文对矩形空心型钢柱的抗火性能进行了试验和理论研究。本文提出了一个计算柱的温度、变形和耐火极限的数学模型。计算结果与实测结果进行了比较。结果表明，该模型是能够预测的方形空心钢柱，填充钢筋混凝土的耐火极限，具有足够的精度，为实用目的。该模型使扩展的数据的耐火方形混凝土填充钢柱，目前主要由填充与钢筋混凝土柱填充与素混凝土柱的数据。利用该模型，可以对任意荷载、柱截面尺寸、柱长、剩余体积分数等重要参数进行方钢管混凝土柱的耐火性能评估。
Experimental and theoretical studies have been carried out to predict the fire resistance of rectangular hollow steel columns filled with bar-reinforced concrete. A mathematical model to calculate the temperatures, deformations, and fire resistance of the columns is presented in this paper. Calculated results are compared with those measured. The results indicate that the model is capable of predicting the fire resistance of square hollow steel columns, filled with bar-reinforced concrete, with an accuracy that is adequate for practical purposes. The model enables the expansion of data on the fire resistance of square concrete-filled steel columns, which at present consists predominantly of data for columns filled with plain concrete with data for columns filled with bar-reinforced concrete. Using the model, the fire resistance of square concrete-filled steel columns can be evaluated for any value of the significant parameters such as load, column-section dimensions, column length, and the percentage of r...
