众所周知,工程实践中使用的高耸塔架构筑物,其截面形状是多种多样的。由于高度大,在塔架和基础的抗风设计中,如何决定体型系数,无疑是一个重要的问题。日本学者卯月英夫等人对铁塔工程实践中常用的五种截面形式,分别作了较为精确的实验和分析并绘出了图表,这些图表直观地表达了五种截面的体型系数,取用较方便,弥补了我国规范的不足,对我们的工程设计计算可能是有帮助的。
As we all know, the tall tower structure used in engineering practice has a variety of cross-sectional shapes. Due to the large height, it is undoubtedly an important issue how to determine the body shape coefficient in the tower and foundation wind resistance design. The Japanese scholar Hao Yueying and others made comparatively accurate experiments and analysis on the five types of cross-section commonly used in the iron tower engineering practice and plotted the charts. These charts intuitively expressed the five types of cross-sectional shape coefficients, making it easier to use. This will make up for the inadequacies of our regulations and may be helpful for our engineering design calculations.
