焊接工字钢梁纯剪状态下超屈曲强度的分析

Analysis of the ultra-buckling strength for welded girder steel in shear force

概括介绍国内外对焊接工字钢梁超屈曲强度研究的各种方法，通过大量的计算和分析，给出焊接钢梁受纯剪破坏的简化模式和极限剪力的计算公式，计算结果与试验结果符合较好．

All methods of analyzing the ultra-buckling strength of welded girder steel are summarized in this paper. Simplified model of collapse in shear force and ultimate shear formula are reached by calculatings and analyzes. Thearetical results are well verified by experimental measurements.
