Performance Based Tests on Cross Laminated Timber - Concrete Composite Floor Panels

Creator:: Blank, Curtis
Abstract:: This project determines the short term and long term effective stiffness values for Cross Laminated Timber (CLT) with a reinforced concrete topping. The reinforced concrete was attached to the CLT panels with interface connections, and different types of interface connections were tested. Throughout this project, there are 31 tests with...

High Strength Reinforcing Bars : Concrete Shear Friction Interface Behavior

Creator:: Nielson, Drew R.
Abstract:: Use of high-strength steel (HSS) reinforcing bars could provide constructability and economic benefits for the construction of structures, reducing the initial and ultimately the life-cycle cost of bridge and building structural elements. This thesis summarizes work performed in a research project on the use of HSS reinforcing bars for concrete...

Shear capacity assessment of corrosion-damaged reinforced concrete beams

Creator:: Farrow, William C.
Abstract:: The research presented here is a study to determine the effect of shear reinforcement corrosion on the shear capacity in conventionally reinforced concrete (CRC) bridge elements. A total of 14 CRC beams were tested using three stirrup spacings (8, 10, and 12-inch). Six of the beams included the influence of...

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....

Development of acoustic emissions testing procedures applicable to conventionally reinforced concrete deck girder bridges subjected to diagonal tension cracking

Creator:: Lovejoy, Steven C.
Abstract:: A need exists to develop a non-destructive testing technique that can identify the formation and propagation of diagonal tension cracks in conventionally steel reinforced concrete deck girder (RCDG) highway bridges in the State of Oregon. Such a technique could be included into a structural health monitoring (SHM) system installed on...

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...

Analysis of Reinforced Concrete Beams with Corrosion Damaged Stirrups for Shear Capacity

Creator:: Higgins, Christopher, Turan, O. Tugrul, and Farrow, William C. III
Abstract:: Corrosion of embedded carbon steel is a leading factor in deterioration of aging conventional reinforced concrete structures. Methods to accurately predict remaining capacity of corrosion damaged elements, especially shear capacity, are lacking. In this paper, ACI-AASHTO approach, Strut and Tie Method, Modified Compression Field Theory, and Response 2000 were used...

Shear repair methods for conventionally reinforced concrete girders and deep beams

Creator:: Howell, Daniel A.
Abstract:: Many conventionally reinforced concrete deck girder bridges (RCDG) and their intermediate supporting bent caps were designed during the Eisenhower interstate era of the 1950’s with the AASHO design equations at the time, which subsequently place higher demand on the concrete. The referenced components may exhibit diagonal cracking due to the...

Design and fatigue behavior of near-surface mounted CFRP bars for shear strengthening of RC bridge girders

Creator:: Johnson, Brandon Ang
Abstract:: Carbon fiber reinforced polymer (CFRP) materials are emerging as an effective means of strengthening and rehabilitating bridges. Near surface mounting (NSM) is a newer technique for application of CFRP for retrofitting of bridge members that provides advantages over conventional strengthening techniques. The technique is still new and uncertainties remain regarding...

Nonlinear finite element analysis of reinforced concrete structures strengthened with FRP laminates

Creator:: Chansawat, Kasidit
Abstract:: The Horsetail Creek (HC) bridge is an example of an Oregon bridge that was classified as structurally deficient and was not designed to withstand earthquake (EQ) excitations. A fiber-reinforced polymer (FRP) rehabilitation was performed on the HC bridge to increase flexural and shear capacities for traffic loads. However, a seismic...
