基于气象数据的复杂钢结构日照非均匀温度场参数化 分析及其效应研究

To efficiently analyze the non-uniform temperature field of complex steel structures under solar radiation，this paper proposes a parametric analysis method based on the Grasshopper platform. By incorporating meteorological data，shadow effects on structures，and simplified temperature calculation formulas，the proposed method enables efficient and accurate analysis of non-uniform solar temperature fields in complex steel structures.To validate the accuracy of the proposed method，the inclined grid steel structure of the Hytera Global Headquarters Building in Shenzhen was selected as a case study. Real-time temperature and meteorological data were collected from multiple monitoring points over a 10-day period. The results show that the root mean square error（RMSE）of daily temperature deviations between the calculated and measured data is less than 12.5%. Additionally，the calculated non-uniform solar temperature fields were translated into temperature loads for construction process simulation. The solar-induced non-uniform thermal effects were studied during construction， and the recommendations for mitigating thermal effects during the design and construction phases were provided.
