摘要
根据传热学和气象学的有关理论,建立了屋面板温度场分析的边界条件和初始条件,并采用通用有限元程序ANSYS对某屋面板的日照温度作用进行了分析。探讨了混凝土屋面板中的日照变温作用,有助于估算结构中的日照温度效应。
The temperature action on a concrete roof is emulated by using FEM package（ANSYS）. Boundary conditions and initial conditions for the emulation of temperature field of the concrete roof are set based on some relevant theories of aerograph and heat transfer. Temperature changes caused by solar radiation on con-crete roof are discussed and it is helpful to estimate the thermal effects of solar radiation on structures.
