Convergence Behavior of Substitute Structure Method in Motems


Abstract eng:
This paper examines the convergence behavior of the Marine Oil Terminal Engineering and Maintenance Standards (MOTEMS) substitute structure method and a secant-stiffness based substitute structure method when implemented in an automated process. It is found that the MOTEMS method does not converge whereas secant-stiffness based method converges when the first estimate of the displacement demand is taken as that of the initial linear-elastic, 5%-damped system. If the initial estimate is sufficiently close to the final solution, the MOTEMS method may also converge. The MOTEMS method, when it converges, leads to a displacement demand similar to that from the secant-stiffness based method. Therefore, the secant-stiffness based substitute structure method may be used in lieu of the current MOTEMS method for structures that are designed according to the MOTEMS requirements.
