摘要
北京新机场航站楼中心区结构超长超大,温度作用影响很大。为研究年温差和局部温差下航站楼的温度变形,首先基于日照影响对航站楼进行温度分区,然后通过类似混凝土框架结构的温度实测,得到不同区域混凝土的温度变化规律,从而得到年温差和局部温差下的新机场航站楼温度分布模型。通过计算日温差下的隔震支座相对水平位移并与实测位移进行比较,验证了温度分布模型的合理性。
The new airport terminal is super long and large, and the impact of temperature is great. In order to investigate the temperature deformation under annual temperature and local temperature, first of all, temperature zoning for terminal building based on sunshine, then, the temperature variation of concrete in different regions was obtained by measuring the temperature of similar concrete frame structure, the new airport terminal temperature distribution model based on the annual temperature and local temperature was established. Finally, the horizontal displacement of the new Beijing airport＇s isolator under daily temperature was calculated and analyzed, compared with the measured displacement, which proves the rationality of the temperature distribution model.
