چکیده

Delamination is probably the most serious form of deterioration I which is commonly found in britlge decks. It ultimately results in large scale spalling necessitating costly repairs. This type of failure is believed to be caused chiefly from salt induced corrosion of the reinforcing steel. An instrument designed to detect delamination, and tests conducted to val:iAate its perf'ormance, are .briefly described •.. The instrument has been used by Texas Highway Department maintenance personnel and has been found to be an effective and practical tool, especially on resurfaced decks. Other bridge deck evaluation techniques investigated were: (a) Corrosion Potential, (b) Acoustic Velocity, (c) Windsor Probe, (d) Schmidt Rebound Hammer, and (e) Direct Tensile Strength. It appears that all of these techniques have merit. It is believed that any of them can be used to search out weak spots or deterioration in bridge decks.

Damage detection of multi-girder bridge superstructure based on the modal strain approaches

The research described in this paper focuses on the application of modal strain techniques on a multi-girder bridge superstructure with the objectives of identifying the presence of damage and detecting false damage diagnosis for such structures. The case study is a one-third scale model of a slab-on-girder composite bridge superstructure, comprised of a steel-free concrete deck with FRP rebars...

Effect of Link Slab on Seismic Response of Two Span Straight and Skew Bridges

Highway bridges are frequently constructed as simple span structures with steel or concrete girders and a cast-in-place concrete deck, spanning from one pier to another. At each end of the simple span deck, a joint is provided for deck movement due to temperature, shrinkage, and creep. Bridge deck joints are expensive and pose many problems with regard to bridge maintenance. Elimination of deck...

Structural analysis of the deck of access bridges in offshore docks under dynamic loading of moving heavy vehicles (Case study: 10 feet concrete deck with prefabricated beam, under the passage of 125-ton bogie)

Ports are the most important economic, political and military bottlenecks. This puts shoreline structures (port) in the class of important structures and they have a crucial role in the countries’ life. Pile and deck wharf and their access bridges and offshore deck (jetties), are one of the parts which are supplier of coupling between the land and the waterfront. Correct and exact estimation of...

How Accurate Is Ground Penetrating Radar (GPR) for Bridge Deck Condition Assessment?

As Ground Penetrating Radar (GPR) is increasingly employed for assessing the condition of bridge decks, quantifying and controlling the quality of GPR data becomes an important challenge. This paper uses a methodology to assess the accuracy of deck condition measures, and demonstrates the methodology in a case study involving real data. The latter are generated during GPR applications on a larg...

Constriction Scour In Pressurized Flow Condition (RESEARCH NOTE)

When depth of flow past a river bridge exceeds opening under the bridge, the flow under the bridge becomes pressurized. The water is directed downward and under the bridge deck, causing increase in velocity and shear stress on the bed thereby increasing bed scour. This is termed as Pressure Flow Scour. The present study investigates the phenomenon of pressure flow scour resulting from a submerg...
