Abstract

This work introduces a structural integrity assessment strategy for Jacket structures based on the finite element MODEL UPDATING and a novel simplified method. Hereof, MODEL reducing and MODEL UPDATING procedure is established based on a optimization technique. Since the number of measured degrees of freedom is most of the time restricted in practice, this paper represents a methodology using the cross MODEL cross mode method (CMCM) in combination with an iterative procedure which uses limited, spatially incomplete modal information. This research is an empirical study on a laboratory MODEL of a jacket structure with the aim of establishing Refined Simplified FE MODEL (RSM) to conduct DAMAGE DETECTION. In addition to elimination of uncertainty effects in the DAMAGE DETECTION results, RSM technique is employed because of practical considerations and also this technique provides a fast damage zone diagnosis procedure. Also, improved reduction scheme is utilized based on static reduction scheme to carry out DAMAGE DETECTION in jacket structure.
