Welcome to the COBRAS Concrete Bridge Assessment Program web site. This site provides information about the program, and how it may be used to perform yield-line analysis of concrete slab, and beam-and-slab bridges.
COBRAS is a yield-line analysis software program for assessing the ultimate load capacity of concrete structures, and in particular, concrete bridge decks.
A number of UK bridge authorities, consultants and overseas organisations are currently using the program to evaluate the load carrying capacity of concrete bridges that have failed assessment using conventional elastic analysis methods.
