土木工程学报第7卷第6期刊载杨更新同志的“三角形断面受压组合构件的修正长细比”一文(以下简称原文),从切力的方向与x-轴成φ角出发,根据静力平衡和变形条件建立6个程式,求得三角形断面受压组合构件缀条体系和缀板体系的整体修正长细比的公式,很有实用价值。但遵照规范121— The article “Complexity Ratio of Compression Triangular Sections Composed of Compressed Components” by Comrade Yang Updates is published in the 6th issue of the Civil Engineering Journal, starting from the direction of the shear force and the x-axis to the angle φ, according to the static Six equations were established for the force balance and deformation conditions. The formula for the overall length-to-thickness ratio of the stripe system and the patchwork system of the triangular section compressed composite member was obtained, which is of practical value. But in accordance with the norm 121 -
