【摘要】 研究了火灾下钢筋混凝土板内的温度场的分布,根据热力学原理,采用傅里叶变换法,在适当的简化假定之后,推导出求解火灾下钢筋混凝土板内温度场的计算公式,并编制了计算程序。将程序计算结果和试验数据进行了对比,两者吻合较好,表明方法具有较高的精度。通过该程序的计算可方便地绘制钢筋混凝土板内的温升曲线,并可为进一步开展高温下钢筋混凝土板的受力性能分析提供依据。更多还原

【Abstract】 The temperature field in reinforced concrete slabs is analyzed ,and on some predigested supposition,the Fourier transformed method is taken to propose the formula of calculating the temperature field in reinforced concrete slabs.A program is developed also.Comparing the calculation of the program with the experiment,it is found that this method is accurate.Through the program,the curves of the temperature in reinforced concrete slabs can be protracted expediently. Furthermore,the achievements offered by this paper have reference for the behavior of reinforced concrete slabs in fire.更多还原
