摘要

本文研究了钢筋混凝土(RC)深梁采用v形外杆体系的抗剪加固技术。重点研究了加固梁的抗剪性能、外杆应力和斜剪破坏时的抗剪能力。通过对照梁和两根加固梁的试验试验，观察外杆对钢筋混凝土深梁抗剪性能的影响。在试验试验的基础上，提出了计算斜剪破坏下外杆应力和加固梁名义强度的理论方法，并在ABAQUS软件中进行了有限元验证。计算得到的加固梁的名义抗剪强度比试验值高10%。该加固技术将钢筋混凝土深梁的脆性剪切破坏转变为延性剪切破坏，提高了混凝土深梁的性能。

Shear Behavior of RC Deep Beam Strengthened by V-Shaped External Rods

This research investigated the shear strengthening technique of Reinforced Concrete (RC) deep beams using a V-shaped external rod system. Shear behavior, the stress in an external rod, and the shear capacity at the diagonal shear failure of a strengthened beam were focused mainly. Experimental tests of control and two strengthened beams were carried out to observe the effect of the external rod on shear behavior of RC deep beam. A theoretical approach to compute the stress in the external rod and the nominal strength of the strengthened beam in the diagonal shear failure were examined based on the experimental test results and verified using Finite Element Method (FEM) in ABAQUS. The computed nominal shear strength of the strengthened beam was 10% higher than the experimental test. The strengthening technique shifted the brittle shear failure to ductile shear failure and improved the performance of RC deep beam.
