Research Abstract

In designing, deflection and stress of the pipe are calculated through structural analysis based on bending ring stiffness EI/D^3. The pipes with equivalent bending ring stiffness would have the same behavior in design. However, it is easily understandable that the behavior of pipe may be influenced not only by EI/D^3, but also by the relationships between E and I. In this research, pit tests, centrifuge tests under 30G and large shaking table tests with 800gal input wave for buried flexible pipes were conducted to evaluate the effects of pipe thickness on the static and dynamic behavior. As a result, it was found that the larger bending strain and radial stress of the pipe occurred with the thinner wall. This result suggests that the probability of the buckling of the pipe is higher on thinner pipes. It is evident that the pipelines for irrigation should be designed in consideration of this fact.
