摘要
横系梁的设置对加强桥梁的整体受力很有好处,横系梁的合理数量和合理位置就显得尤为重要。基于三维实体模型从应力水平和结构位移两个方面对无桥台斜腿刚架桥横系梁的设置进行了分析,研究结果表明:主孔和副孔跨中横系梁、主梁梁端横系梁、斜腿与主梁相交处横系梁必须设置,且横系梁的数量并非越多越好。
Diaphragm locating are very benefit for the whole strengthen of bridge, the number and location of diaphragm are very important. On the basis of 3D solid model analysis, for non-abutment slant legged rigid frame bridge, the diaphragm locating from＂ two aspects of stress level and structure displacement is analyzed. The results indicate that the diaphragm of main span and side span, the diaphragm of girder ends and the diaphragm at the intersection between slant leg and girder must be located, and the more diaphragm number is not better.
