%X The assembled beam bridge is one of the most commonly used and most developed structural types in rapid industrialized bridge construction technology. The hinge joint is the key to the overall cooperative performance of this type of structure, and it is also the most vulnerable part in the service period. This article proposes a monitoring and evaluation method for the lateral collaborative working capability of this type of bridge based on the dynamic strain correlation coefficient index. The proposed method has the advantages of no need to interrupt traffic, easy implementation, concise physical meanings, being independent of short-term traffic load, and so on. Its potentialities to be used in the monitoring and evaluation of the technical state of the hinge joint and the lateral collaborative working performance of the whole bridge have been expatiated theoretically. Through numerical simulation analysis and real bridge monitoring data analysis, it is proved that the method is effective and accurate, and can be applied to the health monitoring system of such bridges
