［摘要］H形截面柱是鋼結(jié)構(gòu)建筑中的主要豎向構(gòu)件,為了有效地降低用鋼量，提高柱子的承載力和穩(wěn)定性，根據(jù)局部穩(wěn)定的規(guī)定，分析出軸心受壓雙軸對稱H形柱截面寬度和高度的關(guān)系式，以及翼緣、腹板尺寸的計算公式。闡述了合理、方便地確定H形截面尺寸的方法，供設(shè)計參考。

Abstract:H-section column are the most important vertical member of steel structures. To reduce the steel quantity and improve the stability of columns，according to the local stability provisions, it analyzes the width-height relationship of the section as well as the calculating formulae of the dimensions of web p

late and flange of the H-section column with two symmetrical axes under axial compression.A simplified method of selecting the section of H-section axial compression steel columns is presented.

Keywords:column;H-section;local stability;axial compression;optimization design
