The use of blended synthetic fibers to reduce cracking risk in high performance concrete (HPC)

Creator:: Bañuelos, José
Abstract:: High Performance Concrete (HPC) is used in our crucial pieces of infrastructure, such as bridge decks, due to its enhanced durability and engineering properties. However, HPC is highly susceptible to early-age cracking. Cracking within the first months of a bridge deck’s lifespan can severely hinder its long-term performance and durability....

Strengthening reinforced concrete beams using FRP composite fabrics : full-scale experimental studies and design concept verification

Creator:: McCurry, David D.
Abstract:: The Horsetail Creek Bridge (HCB), constructed in 1914, is located along the Historic Columbia River Highway in Oregon. The original cross beams from the HCB were substantially deficient in shear strength, particularly for the projected increase in traffic loads. One control beam and three beams with varying configurations of a...

Finite element modeling of reinforced concrete beams externally strengthened by FRP composites

Creator:: Potisuk, Tanarat
Abstract:: Three-dimensional finite element models are developed to simulate the behavior of four fill-scale reinforced concrete beams. The beams are constructed with different fiber-reinforced polymer (FRP) strengthening schemes, and are modeled using ANSYS, a commercially available finite element analysis program. The experimental beams replicate the transverse beams of the Horsetail Creek...

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...

Freeze-thaw durability of reinforced concrete deck girders strengthened for shear with surface-bonded carbon fiber-reinforced polymer

Creator:: Mitchell, Mikal Maxwell
Abstract:: Long-term durability of surface-bonded carbon fiber-reinforced polymer (CFRP) U-wraps 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 freeze-thaw cycling. CFRP...

Scale effects on reinforced concrete beams strengthened for shear with discrete externally bonded carbon fiber-reinforced polymer U-wraps

Creator:: Dawson, Matthew Ryan
Abstract:: Current ACI design provisions for shear in reinforced concrete (RC) beams strengthened with externally bonded carbon fiber-reinforced polymer (CFRP) U-wraps may not adequately account for the effect of scale. This paper describes tests of 6 geometrically scaled beams to identify possible scale effects of such beams. Results indicated that effective...

Examining Carbonation of Calcium Silicate-Based Cements in Real Time Using Neutron Radiography

Creator:: Ghantous, Rita Maria, Goodwin, Margaret N., Moradllo, Mehdi Khanzadeh, Quinn, Sean, Aktan, Vahit, Isgor, Burkan O., Reese, Steven, and Weiss, Jason W.
Abstract:: Carbonatable calcium silicate cement (CSC) is a promising approach to reduce the carbon footprint associated with concrete production. Carbonatable CSC gains strength by reacting with carbon dioxide (CO2). While the concept of carbonation is well known, more information on the curing process is needed. This study focuses on studying the...

Bond strength investigations and structural applicability of composite fiber-reinforced polymer (FRP) rebars

Creator:: Kachlakev, Damian I.
Abstract:: The composite FRP rebars research at Oregon State University was initiated in 1993 principally to develop a non-metallic hollow reinforcement. It was recognized that the tensile properties of such reinforcement are unquestionably superior to steel, but its performance in concrete could be problematic. The bond between FRP rebars and concrete...

Design and environmental performance of near-surface mounted carbon fiber reinforced polymer strips for shear strengthening reinforced concrete bridge girders

Creator:: Goebel, Jacob Hans
Abstract:: During the interstate expansion of the 1950s, many conventionally reinforced concrete deck girder bridges were built throughout the country. These now vintage bridges commonly exhibit diagonal cracking and rate inadequately for shear, thus they are candidates for shear strengthening to extend their useful life. Near-surface mounted (NSM) retrofitting is a...

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...
