Abstract

Abstract

A novel type of sinusoidal corrugated steel-reinforced concrete circular pipe was proposed to present the solution to the electromagnetic shielding problem of ordinary reinforced concrete power pipelines. The segment at the top of circular pipe under bending was selected and studied, and a total of 12 beam specimens were designed and fabricated. Three-point bending tests were performed to acquire the relations between moment and deflection, as well as the failure modes of the beam specimens. It was revealed that the moment resistance of beam specimens decreased as the wavelength and wave height of the encased corrugated sheet increased, and the moment resistance was closely related to the position of the encased corrugated sheet. A fine numerical model accounting for the mechanical properties of encased corrugated sheet and the damage development of concrete was developed by using ABAQUS. The flexural performance of the tested corrugated steel reinforced concrete beams was carefully simulated, and it was shown that the numerically obtained failure modes and moment resistances were in good agreement with the experimental results, thus verifying the accuracy of the developed finite element (FE) model.
