This paper investigates the shear performance of HDC beams reinforced with stirrups. The use of HDC led to limited crack propagation, multiple micro diagonal cracks between the load and support points, and ductile shear failure mode with significant nonlinear response, compared to reference specimens. The contribution of longitudinal reinforcement for shear strength of HCD specimens were larger than RC specimens. An average increment in shear strength of about 19% and a maximum value up to 40% was obtained. A modified formula for evaluating the shear capacity of HDC beam was proposed, and assessed with experimental results.

高延性纤维增强混凝土梁的抗剪性能

本文研究了箍筋增强的HDC梁的抗剪性能。与参考样本相比，HDC的使用导致裂纹扩展受限，载荷和支撑点之间出现多个微对角线裂纹以及具有明显非线性响应的延性剪切破坏模式。纵向钢筋对HCD试样的剪切强度的贡献大于RC试样。剪切强度平均增加约19％，最大值达到40％。提出了一种评估HDC梁抗剪承载力的修正公式，并通过实验结果进行了评估。
