摘要:
焊接箍筋具有节约钢材、节约工时、方便施工、可工业化和标准化生产等性能优势，具有良好应用前景．为研究采用焊接箍筋的钢筋混凝土梁斜截面抗剪性能，分别对4个采用焊接箍筋混凝土梁和4个采用传统绑扎箍筋混凝土梁试件的受剪性能试验研究．结合试验研究，考察了焊接箍筋梁和普通绑扎箍筋梁试件裂缝开展过程和梁受剪破坏形态，分析了各试件抗剪承载能力和箍筋应力发展过程．试验研究结果表明在钢筋混凝土梁中以焊接箍筋替代传统绑扎箍筋是作为抗剪箍筋是可行的，主要表现在焊接箍筋混凝土梁与普通箍筋混凝土梁的裂缝开展、变形发展和破坏形态基本相同，并且焊接箍筋混凝土梁的极限抗剪承载力略高于普通箍筋混凝土梁．另外，经对比分析，焊接箍筋混凝土梁斜截面受剪承载能力稍高于现行规范建议的钢筋混凝土梁斜截面承载能力计算公式的计算结果．本文研究结果可为焊接箍筋混凝土梁的后续研究和工程推广应用提供理论依据．
Abstract:
Welding stirrups techniques have lots of advantages such as saving steel, saving working time, facilitating the construction,
and ease to prompting the production industrialization and standardization, which have good application prospect. To research the
inclined section shear performance of reinforced concrete beams with welding stirrups, the inclined section shear performance of four
concrete beams with welding stirrups and four concrete beams with common tie stirrups were studied respectively. Based on the test
research, the developing process of the crack and the shear failure pattern of welding stirrup beams and common tie stirrup beams
were focused, and the shear bearing capacity and stirrup stress development process of each specimen were also fully studied. It was
showed that it’s feasible to replace the common tie stirrup with welding stirrup as shear stirrup in reinforced concrete beams. Mainly
in the development of the crack and the deformation, the failure forms of welding stirrup beams were similar to the common tie stirrup
beams. In addition, the shear bearing capacity of welding stirrup beams were slightly higher than common tie stirrup beams. On
the other hand, through contrast and analysis, the shear bearing capacity of welding beam slightly higher than the calculation results
calculated by the formula of shear bearing capacity of concrete beam suggested by current code. The study could provide a theoretical
basis for subsequent research and engineering application of welding stirrups concrete beams.
