ABSTRACT

In the E’dong Yangtse River Bridge, the Structural Integrated Safety Management System (SISMS) was set up to improve the traditional Health Monitoring System (HMS) technology (Fig. 1). General structure of the SISMS. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315207681/cd556cd4-4dcf-4efe-8e29-56fc67b8bfbd/content/fig239_1.tif"/>

On one hand, the SISMS aims at the safety information management for the whole life cycle of bridge including the construction period, which can provide more representative information of the structural safety; On the other hand, the SISMS integrates more inspection and monitoring methods with the management of maintenance strategies so as to provide stronger analysis and decision-making tools for the operation & management of bridges. The probability of risk sources and the degree of harm were researched to determine the monitoring key points, the methods and the frequencies. Different sensors were used to acquire the data such as cable forces, deflections and stresses of the girder (Fig. 2). Based on the defects tracking method, data from both the automatic monitoring system and the manual inspection system were evaluated to generate the kernel safety information.

The SISMS of this bridge has been running smoothly for more than five years. An application case of the safety management in operation is presented (Fig. 3), practices have shown that the SISMS can effectively reduce risks and ensure structural safety.
