“…Other works like Junges [10], Wang et al [11], Mankar et al [12] and [13] presented methodologies and casestudies to assess the fatigue reliability of monitored bridges. Junges [10] measured stress in two Brazilian reinforced concrete bridges and concluded that flexural reinforcement failure is unlikely to occur.…”

It is well known that highway bridges are subjected to fatigue as they work under live loads with different frequencies and amplitude. The safety level for fatigue required by Brazilian codes is still unknown, especially for prestressed concrete girders. Also, current studies on fatigue reliability of bridges only evaluate bending. This work assesses the fatigue safety level provided by Brazilian design standards for a concrete highway bridge, using weigh-in-motion (WIM) data of an important federal Brazilian highway, BR-381 (Fernão Dias Highway). The Palmgren-Miner rule is considered to evaluate the service life and reliability indexes, from the fatigue point of view, of prestressed girders designed according to Brazilian codes. Using limited and complete prestressing levels, different traffic volumes are considered. It is found that the fatigue safety levels of longitudinal and transverse reinforcements are larger than the ones recommended by the international literature.

With the development of science and technology, China is building more and more Bridges. The inspection and maintenance of bridge during operation plays an important role in the safety of bridge. Firstly, the research background and significance of bridge structure health inspection are introduced, and the research status and progress of health inspection are analyzed. Then, several commonly used monitoring methods are listed. Based on the comprehensive study of the bridge health monitoring system, the main conclusions are as follows: the bridge health monitoring system is realized through the coordination of several subsystems, including: bridge working environment monitoring, bridge structure overall performance monitoring and bridge structure local performance monitoring. The bridge structural health monitoring system is mainly used in bridge damage identification and bridge safety warning. The bridge structure health monitoring system conforms to the development trend of high technology and will become an indispensable part of the bridge operation in the future.
