摘要
介绍了三维温度场数值计算的基本原理,在确定高温下钢材和混凝土的热工性能的基础上,应用ANSYS有限元分析软件对火灾下型钢混凝土柱三维温度场进行了计算。计算结果与原试验数据吻合得较好,为型钢混凝土柱在高温下及高温后的性能分析创造了条件。
The numerical calculation theory of the 3D temperature field is introduced, and based on the definition of the thermal properties of steel and concrete under the elevated temperature, the 3D temperature field of steel reinforced concrete columns under fire is analyzed by the finite element analysis software ANSYS. The calculations are well consistent with those of tests, which makes it possible to study the performance of steel reinforced concrete columns under and after the elevated temperature.
