摘要
本文结合对试验结果的分析，以平衡方程为基础研究钢筋混凝土梁和钢筋钢纤维混凝土梁斜截面抗剪强度的理论模式。该模式考虑了剪压区混凝土高度及其应力分布、裂缝投影长度、骨料咬合、纵筋销栓作用及钢纤维的增强作用，概念明确、易于理解，与试验结果符合性好。
Based on the analysis of the experimental results and on the equilibrium equations,this paper presents a theoretical model for the shear strength of reinfored concrete and reinforced fiber concerete beams.This model takes into account such factors as the height and stress distribution of shear compression region,the horizontal length of diagonal crack,the action of aggregate interlock and d owel forces.This model gives a clear concept,and is easy to understand as well as in agreement with experimental results.
