火灾下的温度场计算是进行结构抗火设计或研究的重要步骤。采用有限元软件ABAQUS建模,对带楼板单层单跨钢管混凝土平而框架在ISO-834标准火灾作用下的温度场分布进行计算,并采用有关试验数据刈计算结果进行验证。
Temperature field calculation is an important step in fire engineering design or fire safety research. ABAQUS software is used in this paper to calculate the temperature distribution of planar concrete-filled steel tubular frames exposed to the ISO-834 standard fire. For simplification, one-story and one span frames with reinforced concrete slabs are seleeted in the modeling. The caleulation method was verified by four types of test results.
