DESIGN OF STEEL FRAMES USING CALIBRATED DESIGN CURVES FOR BUCKLING STRENGTH OF HOT-ROLLED MEMBERS

摘要

This paper presents a method of designing steel frames allowing for various sections. An analytical investigation was carried out to study the behaviour of a column member with both ends pinned and with various imperfection-to-length ratios. From the obtained results, the magnitudes of imperfection-to-length ratios of various sections are suggested for design and analysis of steel frames allowing for member buckling strength based on the Perry Robertson formula.
