摘要
应用轴压格构柱的有关规定,确定了空腹受弯钢构件孔口上方受压T形截面杆件的最大长细比和开口宽度的最大值;为确保板件具有一定的刚度和强度,提出了空腹受弯钢构件孔口上方腹板和孔间腹板的最小尺寸以及孔间腹板的强度验算式;基于薄板的弹性稳定理论,确定了在纯弯状态下空腹受弯钢构件孔口上方腹板和孔间腹板的最大高厚比.
The study and application practice of web opening steel members subjected to bending (castellated beams) at home are introduced briefly.Using provision of centrally compressed lattice columns,the maximum slenderness-ratio of the T-shaped-cross-section component above the opening and the maximum width of opening are decided.To ensure enough rigidity and strength of component,the minimum size of web above and between the openings and the strength calculation expression of web between the openings are decided.Based on elastic stability theory of thin plate,the maximum high-depth ratio of these two kinds of web under bending is deduced.
