在长安大学渭水校区空旷地按设计、施工标准要求搭建一个独立小屋, 对其外围护结构安装温度、湿度跟踪检测系统, 进行历时897 d的连续检测.在此基础上, 应用CHAMPS软件建立该围护结构的热湿耦合动态仿真计算模型并进行试验验证.通过试验和数值仿真研究该新建建筑外围护结构含湿量随时间的变化规律, 并通过仿真对房屋竣工后8 a中的钢筋混凝土北墙的体积含湿率变化进行预测.结果表明:房屋竣工后近807 d, 预测钢筋混凝土北墙已达到干状态, 随后体积含湿率随季节波动呈年周期变化.“,”At the Wei Shui campus of Chang'an University, an independent building was constructed according to the modern design and construction standards, a temperature and humidity testing system was installed on the outer envelopefor the continuous 897-day testing. Based on the data provided by the system, a dynamic simulation model of the thermal and moisture coupling of the enclosure structure was established with the help of CHAMPS software, and the experimental verification was carried out. Variations of moisture content in the outer enclosure structure of the new building were investigated both experimentally and with the help of numerical simulations. The change of the volume moisture content of the reinforced concrete (RC) north wall in 8 years after completion of the building was predicted by the simulations. The results show that more than two years (nearly 807 days) were required after the completion of the building were required for the RC north wall to reach the dry state according to the predictions, Moreover, it is demonstrated that the changes in volume moisture content with seasonal fluctuations show an annual periodicity with seasonal fluctuations.
