Reliability Models for Bridge Structures

by Andrzej S. Nowak, Univ of Michigan, United States,



Document Type: Proceeding Paper

Part of: Structural Design, Analysis and Testing

Abstract:

The development of rational design criteria requires efficient measures of structural performance. Traditional methods of analysis do not reveal the actual safety reserve (degree of redundancy). Load and resistance parameters are random variables. Therefore, probabilistic methods are used to model behavior of bridges. The paper provides a review of the available methodology, including reliability measures, load models and resistance models for girder bridges.
