Effect of earthquake directional uncertainty on the seismic response of jacket-type offshore platform
In the seismic risk assessment of structures, two main random variables are involved, namely the vulnerability of the structure and the seismic action. The aim of the study presented here is to analyze the seismic behavior of the jacket-type offshore platforms as an expensive and vital structure. Furthermore, the influence of the incidence angle of the seismic action is also investigated by usi...
متن کاملSeismic Reliability Evaluation of the Jacket Structure of an Offshore Platform Based on Nonlinear Time History Analyses
Regarding the previous earthquake damages in offshore structures, as vital structures in the oil and gas industries, it is important that their seismic design will be performed with very high reliability. Accepting the Nonlinear Time History Analyses (NLTHA) as the most reliable seismic analysis method, in this paper an offshore platform of jacket type with the height of 304 feet and with a dec...

Iterative Damage Index Method for Structural Health Monitoring. (December 2009) Taesun You, B.S., Hanyang University, Seoul, South Korea Co-Chairs of Advisory Committee: Dr. Paolo Gardoni, Dr. Stefan Hurlebaus Structural Health Monitoring (SHM) is an effective alternative to conventional inspections which are time-consuming and subjective. SHM can detect damage early and reduce maintenance cost...
متن کاملDrone-Type Wall-Climbing Robot Platform for Structural Health Monitoring
Though civil structures need constant maintenance and inspection of the structural health condition and safety of the users, the accessibility is getting harder and harder because of their gigantic height and size. To overcome this problem, several approaches for wall-climbing mechanism have been introduced for many decades; however, there is no assured solution yet. One of the reasons why exis...
متن کاملA New Strategy for Structural Health Monitoring based on Structural Destroyed Mode and Data Correlation
This paper provides a new strategy for study of Structural Health Monitoring, and discusses establishment of structural safety monitoring system based on the structural destroyed modes and data correlation. Two concepts, structural destroyed mode and data correlation, are given and discussed. The structural destroyed mode refers to the pattern of certain structural state or situation that some ...
