Abstract

Abstract

The requirements of concrete printing technique make it impossible to install stirrups in beam members. Therefore, printed concrete beam members with different truss-type reinforcements were designed, and static loading tests were carried out. Normal section and oblique section failure tests of printed concrete beams with different truss numbers and sizes were carried out respectively. The failure characteristics, load-deflection curves under static load were studied. The test results showed that the flexural capacity of the printed truss-type reinforced concrete beam with appropriate reinforcement was similar to that of the concrete beam with single reinforcement, but the abdominal reinforcement of the truss improved the stiffness of the beam. There was a big difference between the shear bearing capacity of the oblique section of the bending area of printed truss-type reinforced support and the calculated bearing capacity of the oblique section of reinforced normal concrete where the reinforcement was bent.
- 3D printed concrete,
- truss-type reinforcement,
