A constitutive model of concrete confined by steel reinforcements and steel jackets
Canadian Journal of Civil Engineering, 2005In this paper, a total of 60 concrete cylinders 30 cm in diameter and 60 cm in length confined by steel jackets of different thicknesses and different types of lateral steel reinforcements are tested to obtain the stress–strain curves of the cylinders. A constitutive model is proposed to describe the behavior of concrete confined by steel reinforcement,

Delayed non-fragile H∞ control for offshore steel jacket platforms
Journal of Vibration and Control, 2013This paper is concerned with a delayed non-fragile [Formula: see text] control scheme for an offshore steel jacket platform subject to self-excited nonlinear hydrodynamic force and external disturbance. By intentionally introducing a time-delay into the control channel, a delayed robust non-fragile [Formula: see text] controller is designed to reduce ...

Multi-loop feedback control of offshore steel jacket platforms
Computers & Structures, 1999Abstract In this paper, a new multi-loop feedback-control design is developed and applied to an offshore steel jacket platform. The platform is subjected to wave-induced self-excited hydrodynamic forces. The nonlinear Morison equation is employed to estimate these wave forces.
