This paper describes a method of performance evaluation and remaining life prediction for an aged reinforced concrete (RC) T-girder bridge by J-BMS RC version via close visual inspection data, and also verifies the assessment results obtained as outputs from the Bridge Rating Expert System (RC-BREX) which is a subsystem of the J-BMS, to evaluate the effectiveness of the system. The Bridge Manag...

Padma Multipurpose Bridge (PMB) is one of the most important projects in history Bangladesh due to its regional importance, economic benefit, and primary connectivity one-third population country. The bridge 6.15km long, connecting ends Mawa Janjira Bangladesh. entire project challenging construct complex design as it contains both four-lane highways train tracks supported by a double-deck comp...

The Ground Penetrating Radar (GPR) has been studied for a long time as a non-destructive evaluation (NDE) technology for inspection of concrete structures. Currently, the most widely used technique for interpreting GPR data of concrete bridge decks is the one that based on the amplitudes measured at various interfaces such as asphalt-concrete, top rebar, or slab bottom. The assumption behind th...

Analysis methods for computing the flutter speed of bridges stabilized against by stationary wings are presented. The placed outboard bridge deck to achieve a large lateral eccentricity, which enables them produce enough aerodynamic damping effectively raise speed. Given focus on flutter, other wind effects neglected. analysis can thus be carried out in frequency domain. most sophisticated meth...

In the 1970's it was reported that there were approximately 2300 track miles of timber railroad bridges in the United States and Canada. For short spans, they offer an attractive alternative to other types of bridges as they are economical, faster to construct and easy to maintain. Current design practices do not allow an independent consideration of the effects of the dynamic loads in sizing o...

In this work the aeroelastic stability of long-span bridge decks is numerically investigated. A simulation model is presented by which the aerodynamic fields and the structural motion are simultaneously and jointly simulated. The bridge deck is schematised as a bidimensional rigid body subject to elastic restraints corresponding to the torsional and the vertical degree of freedom, and the ALE f...

This paper presents results from an extensive experimental study on hydraulic performance of new rectangular bridge deck drains developed by the Texas Department of Transportation (TxDOT) Bridge Division. It fits between the deck reinforcement with the top of the drain flush with the bridge surface and does not interfere with the structural connection of the bridge rail to the deck. Experiments...
