摘要
为了经济合理地设计叠合梁 ,应用灰色系统理论 ,对均布荷载下钢筋混凝土叠合梁的斜截面积承载力及其关联因素进行关联度分析。结果表明 ,对叠合梁斜截面承载力影响最大的是预制梁混凝土强度等级 ,其次是叠合层混凝土强度等级、叠合特征参数αh。
The shear resistance on the reinforced concrete composite beam subject to uniform distributed load are analyed by grey system theory as well as the correlation factors. The analysis result shows that the first factor influences the shear resistance on the reinforced concrete composite beam is precast concrete strength grade and the factors of pastcast concrete strength grade、 composite characteristic parameter α h,the composite characteristic parameter α m has the least influence.
