Investigation of the behavior of diagonally cracked full-scale CRC deck-girders injected with epoxy resin and subjected to axial tension

Creator:: Smith, Matthew T. (Matthew Todd)
Abstract:: Article 1: Behavior of Epoxy Injected Diagonally Cracked Full-Scale CRC Deck-Girders. Many cast-in place reinforced concrete deck-girder bridges (RCDG) remain in the national inventory and exhibit diagonal cracking. Epoxy injection has been in use for several decades as a method for sealing diagonal cracks, but the effects on girder behavior...

Analysis of conventionally reinforced concrete deck girder bridges for shear

Creator:: Potisuk, Tanarat
Abstract:: Large numbers of 1950's vintage conventionally reinforced concrete (CRC) bridges remain in-service in the national bridge inventory. Many of these bridges are lightly reinforced for shear. Evaluation of these bridges to prevent unnecessary and costly repairs requires refined analytical techniques. This dissertation presents finite element (FE) modeling and comparisons of...

Environmental durability of reinforced concrete deck girders strengthened with surface-bonded carbon fiber-reinforced polymer

Creator:: Sopal, Gautam Jayant
Abstract:: Long-term durability of surface-bonded carbon fiber-reinforced polymer (CFRP) for shear strengthening of reinforced concrete (RC) bridge members remains uncertain due to the limited field experience with these materials. This paper provides experimental results from the testing of full-scale RC bridge girder specimens after exposure to prolonged environmental exposure and combined...

Investigation of the fatigue behavior of diagonally-cracked CRC deck-girders repaired with CFRP

Creator:: Williams, Grahme T.
Abstract:: Fiber reinforced polymers (FRP) are becoming more widely used for repair and strengthening of conventionally reinforced concrete (CRC) bridge members. Once installed, the repair may be exposed to millions of load cycles during service life. The anticipated life of FRP repairs for shear strengthening of bridge members under repeated service...

Flexural steel anchorage performance at diagonal crack locations

Creator:: Triska, Mary Ann
Abstract:: Large numbers of reinforced concrete deck girder bridges that were constructed during the interstate system expansion of the 1950s have developed diagonal cracking in the stems. Compared to the present AASHTO-LRFD standards, the provisions of the 1950s allowed for higher shear stress in the concrete, thus reducing the amount of...

New acoustic emission applications in civil engineering

Creator:: Schumacher, Thomas
Abstract:: Non-destructive testing methods and applications have become of increasing interest due to the worldwide aging and deteriorating infrastructure network. In the field of Civil Engineering, bridges and bridge components as well as non-structural elements such as roadway pavements for example, are affected. In particular, the Acoustic Emission (AE) technique offers...

Testing and evaluation of flexural reinforcing bars terminating in columns

Creator:: Koester, Carl C.
Abstract:: Capacity of transverse 1950's vintage reinforced concrete deck girder bridge bent caps with large straight bar anchorages were investigated and evaluated. Eleven subassemblage column specimens were examined with different anchorage lengths, bar groupings, amount of transverse steel, and externally applied axial force. Test results showed an increase in anchorage capacity...

An investigation of Oregon weight-in-motion data for bridge rating implementation and evaluation

Creator:: Pelphrey, Jordan Michael
Abstract:: The LRFR Manual, within commentary Article C6.4.4.2.3, contains provisions for development of site-specific live load factors. In Oregon, truck Weigh-in-Motion (WIM) data were used to develop live load factors for use on state-owned bridges. The factors were calibrated using the same statistical methods that were used in the original development...

Influence of diagonal cracks on negative moment flexural anchorage performance in reinforced concrete bridge girders

Creator:: Goodall, Joshua K.
Abstract:: Large numbers of vintage reinforced concrete deck-girder bridges remain in the national bridge inventory. Many of these exhibit diagonal cracking and other distress. Due to the design practices of the time, it is common to observe cracks at locations where flexural reinforcing steel is terminated along the span. The presence...
