摘要

The high-temperature sensitivity of the mechanical properties of composite ice and pure ice materials makes thermal risk prediction and careful thermal management essential for ensuring the stability and durability of composite ice shell buildings. Based on previous studies on the radiation spectra of composite ice and pure ice, this study established two dynamic solar radiation and heat transfer models for composite ice and pure ice structures. Compared with temperature data from previous field tests, the average root mean square errors for the composite ice structure model and pure ice structure model were 0.86 °C and 0.91 °C, with mean absolute errors of 0.74 °C and 0.79 °C, respectively. In addition, the degree of influence of four meteorological parameters on the surface temperature of both ice structures was investigated, covering indoor and outdoor air temperatures, outdoor wind speed, and solar irradiance. The application of the two models was further extended through response surface methodology experiments to investigate the variations in the surface temperature and thermal risk of ice structures under the simultaneous effects of meteorological parameters with significant impacts, the addition ratio of reinforcing materials, and the structural thickness. Multivariate regression prediction models for the surface temperatures of ice structures were subsequently established. The results provide a method for simulating the dynamic solar radiation and heat transfer in spectrally selective ice structures in real time, as well as directly predicting the thermal risk, thus providing important references for the future operation and maintenance of composite ice shell buildings.
