ANALYSIS ON NON-UNIFORM TEMPERATURE FIELD OF STEEL GRIDS OF BEIJING DAXING INTERNATIONAL AIRPORT TERMINAL BUILDING CORE AREA CONSIDERING SOLAR RADIATION
-
摘要: 温度荷载在大跨空间结构的设计与施工过程中十分重要，由于太阳辐射以及各构件之间遮挡关系的复杂性，结构中的温度场一般是不均匀的。该文基于消隐算法，实现了圆截面杆系构件日照阴影的计算方法，编制了能够考虑地理气象信息的太阳辐射量计算程序。以北京大兴国际机场钢网格结构为背景，在ANSYS软件的热分析模块中模拟了结构的瞬态温度场，并对瞬态温度场的重要求解条件进行了讨论。结果表明，考虑太阳辐射后，大跨空间结构中的温度场具有明显的非均匀性与时变特征，日照阴影在温度场模拟中不可忽略。对于较为复杂的大跨空间结构，该文建议的温度场模拟方法为施工过程的精确模拟提供了重要基础。Abstract: Temperature is an important load in the design and construction process of large-span spatial structures, and a temperature field is generally non-uniform due to the complexity of solar radiation and the occlusion relationship between structural members. Based on blanking algorithm, a special method is realized to calculate the sunlight shadow of round section members, and the solar radiation calculation program capable of considering geographic and weather information is developed. Taking the steel space truss of Beijing Daxing International Airport as an example, the transient temperature field of the structure is simulated using the thermal analysis module of ANSYS software, and several important solution conditions are discussed. The results show that:the temperature field in the large-span spatial structure shows obvious non-uniformity and time-varying characteristics after considering solar radiation, and the sunlight shadow should not be ignored. For large-span spatial structures which are relatively complex, the simulation method of temperature field proposed provides an important basis for the accurate simulation of the construction process.
