As reliability based methods gain increased acceptance, there is greater opportunity to use scarce resources more efficiently while maintaining a prescribed level of reliability of a structure throughout its service life. The goal is to provide management decisions that will balance lifetime system reliability and expected lifecycle cost in an optimal manner. This study proposes a system reliab...

This paper discusses the implementation of a Structural Health Monitoring system for a FRP bridge structure using vibration-based monitoring techniques. The need to monitor the long-term performance of fiber reinforced polymer (FRP) composite bridge structures prompted the installation of a vibration-based structural health monitoring system on a recently-built FRP composite highway bridge in C...

In the reliability assessment of a bridge in operation with regards to its ultimate limit state, it should be noted that strengths members and effects traffic load vary continuously over lifespan due structural deterioration changes environment, respectively. Therefore, is essential collect relevant data, incorporate extracted information into time-dependent analysis. However, previous studies ...

This study analyzes the applicability of different damage indexes for bearings, focusing on time-dependent deterioration materials and bond-slip behavior between steel concrete caused by chloride erosion. First, methodology is proposed, encompassing materials, behavior, quantification bearing, fragility analysis bearings. Next, an offshore bridge used as example to investigate detailed elements...

Abstract The assessment of infrastructure conditions is at present a topic great interest and importance, as well challenge. This paper presents case study the Samuel De Champlain Bridge (Montreal, QB, Canada), an outstanding stay cable bridge equipped with comprehensive monitoring system (SHM). Among other SHM features, particular attention was paid to implementation strategic corrosion system...

In structural health monitoring (SHM), variations of dynamic properties are paramount to indicate the status structures. Structural time variant due various long-term effects (e.g., deterioration) and periodic temperature, humidity, traffic). Sometimes will interfere with quantification effects. Though important, there still limited research studies aiming distinguish these two Given amount SHM...

The natural aging, environmental impact, and appropriate design are certainly playing a serious role in safety of the bridges function. The functional safety of bridge constitutes a prime element of the transportation system serving commuters, passengers and freight. According to Federal Highway Administration, the steel bridges share represents a large amount of the United States' bridges. In ...
