Relationship between bearings type and their most common anomalies

ABSTRACT: Bearings have an important role in bridges functioning. An anomaly in a bearing affects the bridge’s global behavior, becoming a structural problem. According to statistics, conservation costs of bearings represent around 5 to 7% of the global conservation costs in road bridges. With such significant values, anomalies in bearings must be considered a structural safety problem as well as bridges management problem. Therefore, it is fundamental to establish an efficient inspection and diagnosis system where the different types of bearings have their anomalies Identified and related with their causes.
