Failure Mode Identification

Increasing axle loads and traffic density made bridge accidents happened very often in China which caused the bridge safety assessment method in dire need. As a method for bridge safety assessment, the structural reliability analysis is widely accepted. An important part of system reliability estimation is to identify the subset of significant failure modes. In this paper, a stage critical strength branch and bound algorithm is proposed for the failure mode identification of bridge systems. The proposed method is implemented in the combination with the finite element package ANSYS and the MATLAB procedure, and is illustrated with the help of a truss bridge example. This algorithm is found efficient and reasonably accurate, and it can be applied to any kind of bridge systems without having to do much additional programming.

This paper presents a failure analysis for a steel open-type Sabo dam (hereafter, steel open dam) against an extreme boulder debris flow load (hereafter, level II load) by a two-step analysis. The first step analysis is to estimate the level II load against the rigid wall by using the revised distinct element method (DEM). In the second step, the failure mechanism of a steel open dam is examined by using a dynamic elastic plastic analysis, in which the level II load-time relations obtained by the first analysis are multiplied by a reduction factor and then used. For the second step, the effects of the flange joint and dent deformation of the connection between column and beam are considered. Finally, a simple entire uniform load onto the steel open dam is proposed as a level II load model for the safety assessment.
