YD／T 5131-2005 移动通信工程钢塔桅结构设计规范（英文版）.pdf简介：
YD/T 5131-2005 "Mobile Communications Tower Mast Structure Design Specifications" (英文版) 是中国的一项通信工程设计标准，它详细规定了移动通信基站中钢塔桅结构的设计要求、计算方法、构造详图以及相关检验与验收的规定。该标准适用于移动通信基站的高耸结构，如天线塔、信号塔等的建设，对钢塔的强度、稳定性、耐腐蚀性、抗震性等性能有严格的规定。
"YD"是中国邮政的英文缩写，"T"是技术标准的意思，"5131"是标准编号，"2005"表示发布年份。"Mobile Communications Tower Mast Structure Design" 指的是移动通信塔桅结构设计，"Specifications" 则表示设计规范。英文版的PDF文件可能包含图表、技术参数、设计参数和详细的工程实施指南，是工程师在设计和施工移动通信塔桅时的重要参考依据。

1Such requirement is provided in order to ensure that the binding ratio of internal and external anglesteelataconnectionnodeisnotlessthan75%. 2If the space between major member and web member is too large,it is disadvantageous to rigidity outside gusset plate surface; if too small,it is not convenient for construction. 3When the angle a between the gusset plate edge and the member axis is less than 15°,the gussetplate is narrow and long,disadvantageous forrigidity outsidegussetplate surface. 4The material is saved and stress eccentricity is reduced due to oversize thickness of gusset plate oy increasing rigidity of gusset plate rims (or adding stiffening plate)
