Importance Sampling Technique for Simulating Time Histories for Efficient Rainflow Fatigue Analysis
Publisher: American Society of Civil Engineers
Abstract: Frequency domain analysis of a dynamical system yields the response spectral density. There are many spectral fatigue methods for evaluating the mean fatigue damage from a stress spectrum, but they are only approximate. ...

Efficient Method for Approximating the Joint Extreme Value Distribution of Multivariate Stationary Gaussian Processes
Publisher: American Society of Civil Engineers
Abstract: The joint extreme value distribution (JEVD) of multivariate random processes is important for evaluating the system reliability of a structure subjected to random vibrations. There are very limited analytical approaches ...
Understanding the Dynamic Coupling Effects in Deep Water Floating Structures Using a Simplified Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The global dynamic response of a deep water floating production system needs to be predicted with coupled analysis methods to ensure accuracy and reliability. Two types of coupling can be ...
Extreme Response Analysis of Floating Structures Using Coupled Frequency Domain Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the dynamic analysis of a floating structure, coupled analysis refers to a procedure in which the vessel, moorings, and risers are modeled as a whole system, thus allowing for interactions ...
Local Scour and Flow Characteristics around Pipeline Subjected to Vortex-Induced Vibrations
Publisher: ASCE
Abstract: Although local scour around submarine pipelines has been extensively studied in the last few decades, understanding of the mechanism of local scour around pipelines is still in its infancy stage due to the complex nature ...
