摘要
纤维混凝土是一种利用纤维材料增强混凝土性能的复合材料。纤维对混凝土的增强效果主要起决于纤维-混凝土基体的界面粘结性能。利用复合材料的剪滞理论对纤维混凝土的纤维-混凝土基体的界面力学传递进行分析,得出了纤维承受拉应力和剪应力的表达式,并分析了纤维对混凝土的增强效果。
Fiber reinforced concrete is a kind of composite material reinforced by fiber.The effect of reinforcement is determined primarily by the bonding interface property.The stress transfer of fiber-concrete interface is analyzed by shear-lag theory in this paper and the expression of the tensile stress and compression stress were gained.And finally the factor of affecting the effect of reinforcement was discussed.
