The editor of the standard《Technical regulation of design for steel tubular tower structures of overhead transmission line》(DL/T 5254-2010) explained compiling process、related background、and main points. It is included these contents as follows:the simplified analyses idea of the Eiffel effect; the theory and hypothesis of controlling vortex street vibrance; error correction for shape coefficient of LOAD CODE; the steel strength grade is selectable and using note; the computational model of steel tubular tower; the way of designing classical joint;building relation for element’s Slenderness Ratio、Diameter-Thickness Ratio and Yield-Strength Ratio of steel;consummating and revising design method of flanges; suggested pertinent textural measure of steel tubular tower structures. It is useful valuable reference for user of this standard.
