SMART‐DECK: Multifunctional carbon‐reinforced concrete interlayer for bridges

Evaluation of Sealers for Concrete Bridges

Recent Innovation for Concrete Highway Bridges

A new generation of concrete highway bridges has recently been built in Canada using new design concepts and advanced materials for reinforcing and prestressing concrete . This paper describes briefly the design and construction of three bridges. The first smart concrete highway bridge (Centre Street, Beddington Bridge, Calgary, Alberta) is prestressed by carbon fiber reinforced plastic (CFRP) ...

Probabilistic Model for Degradation of Concrete Strength of Bridges

This paper investigates the degradation mechanism and tendency of concrete strength of existing bridges. Concrete strength is a time-variant property which usually increases rapidly during the first few years but more slowly as it approaches a nearly uniform level. For bridges sUbjected to environmental attack, the concrete strength can decrease with time. More than 700 concrete strength data h...

Development and Practical Application of a Lifetime Management System for Prestressed Concrete Bridges

A practical Bridge Management System has been developed by the author, which is referred to as the Japanese Bridge Management System (J-BMS) for existing concrete bridges. This paper introduces a newly developed bridge management system for the prestressed concrete (PC) bridges (J-BMS PC version) which is integrated with the PC bridge rating expert system (PC-BREX). The proposed system is able ...

A methodology for Determining the Seismic Vulnerability of Old Concrete Highway Bridges by Using Fragility Curves

Past earthquakes have demonstrated that old RC bridges may be seismically vulnerable. Bridge responses during the last decades illustrated the necessity of the seismic assessment of bridges especially those which were designed with old codes. In this research an existing concrete bridge representative of the most common bridges in the highway system in Iran are studied. Push over and nonlinear ...
