| 摘 要： | 在钢结构设计中,分析结构温度效应、确定施工合拢温度的难点在于确定温度场分布。为了提出一种计算露天日照条件下钢结构构件温度场分布的方法,采用CFD数值模拟,运用Gambit软件进行建模,Fluent软件进行有限元求解,计算出工字型、箱形构件在北京2009年5月12日各个测温时刻的温度场。通过数值模拟计算结果与相应试验测温数据的对比,验证了所提分析方法的有效性。通过算例,分析讨论了影响钢结构构件温度场的各个因素,为工程设计提供参考。

| Abstract: | In the design of steel structure,it's difficult to determine the distribution of temperature,which is the base to calculate the effect of temperature and determine the temperature of closure operation.For proposing a method of calculating the temperature field of steel members in sunshine,computation fluid dynamics(CFD) method is employed to calculate the temperature field of the I-section and box specimens at every measuring time in Beijing on May 12th 2009,using the Gambit software to model and using the ... |
