| Strength of Steel-Concrete Composite Pipe Reinforced with Spiral Rib Shunso Kikukawa, Kohzo Akahide, Yasuhiko Ueki, Taishi Tsukahara |

Synopsis : This study deals with the applicability of a newly developed pipe, which has spiral ribs on its inner surface, thereby making it a composite structure. Mechanical properties of the composite pipe were investigated through push-out, compression and bending tests. Main conclusions obtained are as follows: (1) Bond stress can satisfy the ordinarily required value for the composite pipe having ribs more than 8 mm high. (2) Nominal bond stress increases steadily with increasing the number of ribs. (3) Structural member made of spiral ribbed pipes and concrete can be designed and used as a fully integrated body. |
