Abstract: Pipeline pullback is a crucial part of horizontal directional drilling (HDD) construction. Accurate pullback force prediction is the prerequisite for ensuring construction safety. However, owing to the influence of factors ...

Abstract: Long-distance oil pipelines consume extensive energy during the operation. Accurate prediction of pipeline’s energy consumption is the basis of intelligent management and energy-saving plan. This work demonstrates an ...

Abstract: This paper introduces a new shear reinforcement beam-column joint mechanism—the twisted opposing rectangular spiral—and carries out numerical and experimental investigates. Converting the conventional discontinuous shear ...
