The carrying capacity of pipes with initial dents under lateral bending is studied experimentally in the present work. Several factors of the initial dent are taken into consideration, namely the shape, size, position and depth of the dent. In the experiment, three-point bending tests on the scaled pipe specimens are performed in two steps. In the first step, the initial dent is introduced onto the pipe, with certain combinations of factors. Then in the second step, the residual carrying capacity of pipes with initial dents is obtained by lateral bending tests. The most severe situation is identified out in terms of the shape, size and position of initial dents. Finally, the relationship between the residual bending carrying capacity and initial dent depth is concluded.
