摘要
为提高建筑钢结构侵蚀性能分析准确性,文章提出空气污染对建筑钢结构侵蚀性能的影响建模方法。获取空气污染物的时空分异特征,构建空气污染对建筑钢结构侵蚀性能的影响模型,分析建筑钢结构与空气污染的关系。首先利用不同模型分析方法获取日均浓度散点图,可知文中方法测试结果与实际值更加贴近。再利用四组模型得到侵蚀性能预测曲线,可知文中模型的Corr值较高,由此可见此次构建模型拥有更好的建筑钢结构侵蚀性分析效果。
In order to improve the accuracy of corrosion performance analysis of building steel structure,this paper proposes a modeling method for the influence of air pollution on corrosion performance of building steel structure.The spatial and temporal variation characteristics of air pollutants were obtained,and the influence model of air pollution on the corrosion performance of building steel structure was constructed,and the relationship between building steel structure and air pollution was analyzed.Firstly,the scatter plot of daily average concentration is obtained by using different model analysis methods,which shows that the test results of this method are closer to the actual values.Using four groups of models to get the erosion performance prediction curve,it is concluded that the model in this paper has a higher Corr value,which shows that the construction model has a better effect on building steel structure erosivity analysis.
