ZEBRA - Condition Survey of Bridges on Demolition (AGB1998/101)
Overview
Background & policy context:
Every year several bridges of the federal road network are demolished due to changed demands, if they are an obstacle to expansion or if are reaching the end of their service life. During the demolition of these bridges valuable information can be gained. This information would be obtained at great expense if the structure has to maintain its function. Destructive testing methods can be applied without restriction and the results of earlier investigations can be verified.
Objectives:
The aims of the research project are the creation of a framework for registration of demolished bridges, the central collection and processing of the data and the development of detailed procedures for registration of the condition.
In addition, the project should provide new knowledge about damage and failure mechanisms as well as new knowledge for checks of similar objects.
The research project allows coordinated collection of the gained information in the long term. This guarantees a uniform methodology and data structure. Therefore, the results are comparable and statistically processable.
