Abstract:
The extreme value analysis of various actions on structures was the basis of the determination of the actions design values for new structures and actions assessment values for service structures. These methods about analysis of extreme value of actions were discussed on three aspects which were the estimation of truncated distribution of actions, the estimation of maximum value distribution of actions as well as the assessment of uncertainty of estimation result. Limitations and deficiency were found in all these aspacts:firstly, the fitting method for base distribution of actions lacked in objectivity and was inaccurate; secondly, it was not appropriate to analyze the maximum value distribution of actions using stochastic process model; thirdly, the uncertainty in the estimation of extreme value was neglected, and some imperfections were pointed out in details. Finally, suggestions to the main problems were presented, which estimated the base distribution of actions using threshold model estimated the generalized extreme value distribution of maximum value of actions directly using the point process model, and considered the uncertainty of estimations to select the appropriate one.
