基于二次受力迭合梁斜截面受力性能和钢纤维混凝土材料特性，分析了钢纤维混凝土迭合梁截面的剪应力分布规律。
Based on the double stress of steel fiber reinforced concrete (SFRC) composite beams and their material performance, a law of shear stress redistribution in SFRC composite beams is studied.
认为在一定锚固预应力作用下，梁底反力沿梁长呈二次抛物线分布，而直线及均匀分布。
It is put forward that under a definite prestressed force, the distribution discipline of the counterforce along the length of beam is quadratic parabola rather than linear or uniform one.
