Book excerpt: "New materials and design methods are being investigated for the design of bridge components to alleviate the current devastating corrosion problems. A research project was initiated at the University of Missouri (UM) and the Missouri Department of Transportation (MoDOT) to develop a nonferrous hybrid reinforcement system for concrete bridge decks by using continuous fiber-reinforced-polymer (FRP) rebars and discrete randomly distributed polypropylene fibers. This hybrid system may eliminate problems related to corrosion of steel reinforcement while providing requisite strength, stiffness, and desired ductility, which are shortcomings of FRP reinforcement system in reinforced concrete"--Abstract, leaf iii.

Available in PDF, EPUB and Kindle. Book excerpt: Deterioration of concrete structures subjected to aggressive environmental conditions is attributed to corrosion of the steel reinforcement. Highway bridge deck slabs in particular are exposed to de-icing chemicals that attack the internal reinforcement after the initiation of cracks on the top surface. The use of glass-fibre reinforced polymer (GFRP) bars as top reinforcement in the deck slab greatly increases the resistance of the deck slab to corrosion. Conventional steel bottom reinforcement allows the structural deck system to achieve an overall ductility close to that of a conventional steel-reinforced bridge deck. This hybrid reinforcing system presents a compromise between corrosion-free FRP reinforcement, with low ductility and high cost, and ductile, inexpensive conventional reinforcement, with poor corrosion resistance. This thesis presents the experimental program of a full-scale hybrid-reinforced bridge deck model. Five static tests were conducted using a simulated design wheel loading to investigate the suitability of a hybrid reinforcing system for highway bridge deck slabs. The behaviour of the experimental model is evaluated and compared with other experimental and analytical models as well as code predictions. Based on this investigation, recommendations are made regarding the applicability of hybrid reinforcement for concrete highway bridge decks.

This book was released on 2020 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on utilizing steel fiber vs concrete reinforcement in bridge deck to replace more traditional reinforcing bars is sparse, therefore a research into this topic is interesting to identity opportunities for speeding up of construction by avoiding laying and tying reinforcement and verifying clear cover to reinforcing bars which is one of the most time-consuming processes involved in construction. This study investigates the efforts of steel fiber on the bridge deck from the strength and economical implementation. Four concrete mix design with vary steel fiber dosages of 0.0%, 0.5%, 1.0%, and 1.5% used in this study. The physical properties of steel fiber reinforced concrete were calculated through various tests at the Civil Engineering Laboratory Building. In total, 12-cylinder specimens of 4-inch diameter and 8-inch height, 12-cylinder specimens of 6-inch diameter and 12-inch height, 12- beam specimens of 6x6x20 inch and 12-slabs 45x20x3.5 inch were produced and tested after 28 days of curing. The specimens were tested for their compression, modules of rapture, flexural behavior as well as the split tensile test.The experiments revealed that the increase in the dosage of steel fiber fraction increases the compressive strength of the concrete by 17.4%, 23.5%, and 19.6% respectively for normal weight concrete without steel fiber. The breakout strength of concrete in tension increased by 21.6%, 33.6% and 54.8% for 0.5%, 1% and 1.5% volume fraction of steel fiber in concrete respectively. It is also found that adding steel fiber improves the ductility of slabs specimens behavior, the area under the load-deflection curves increases compare with normal concrete. Also adding steel fiber to the concrete matrix decreases the crack width and preventing the sudden collapse as in normal concrete. The cost analysis showed that utilizing steel fiber as concrete reinforcement in bridge decks improved the opportunity for economical construction, speeding up construction, more corrosion resistant options over the conventional reinforcing bars as corrosion of reinforcing steel in the most common path to failure of the bridge deck.

Available in PDF, EPUB and Kindle. Book excerpt: The research presented in this dissertation focuses on the material characterization of ultrahigh performance fiber reinforced concrete (UHP-FRC) at both the microscopic and macroscopic scales. The macroscopic mechanical properties of this material are highly related to the orientation of the steel fibers distributed within the matrix. However, the fiber orientation distribution has been confirmed to be anisotropic based on the flow-casting process. The orientation factor and probability density function (PDF) of the crossing fiber (fibers crossing a cutting plane) orientation was obtained based on theoretical derivations and numerical simulations with respect to different levels of anisotropy and cut planes oriented arbitrarily in space. The level of anisotropy can be calibrated based on image analysis on cut sections from hardened UHP-FRC prisms. Simplified equations provide a framework to predict the mechanical properties based on a single fiber-matrix interaction rule selected from existing theoretical models. Along with the investigation of the impacts from different curing methods and available post-cracking models, a versatile parameterized uniaxial stress-strain constitutive model was developed and calibrated. The constitutive model was implemented in a finite element analysis software program, and the program was utilized in the preliminary design of moveable bridge deck panels made of passively reinforced UHP-FRC. This deck system was among the several alternatives to replace the problematic steel grid decks currently in use. Based on experimental investigations of the deck panels, failure occurred largely in shear rather than flexure during bending tests. However, this shear failure is not abrupt and usually involves large deformation, large sectional rotation, and wide shear cracks before loss of load-carrying capacity. This particular shear failure mode observed was further investigated numerically and experimentally. Three-dimensional FEM models with the ability to reflect the interaction between rebar and concrete were created in a commercial FEM software to investigate the load transfer mechanism before and after bond failure. Small-scale passively reinforced prisms were tested to verify the conclusions drawn from simulation results. In an effort to improve the original design, several shear-strengthened deck panels were tested and evaluated for effectiveness. Finally, methods and equations to predict the ultimate shear capacity were calibrated. A two-dimensional frame element based complete moveable bridge finite element model was built for observation of bridge system performance. The model contained the option to substitute any available deck system based on a subset of pre-calibrated parameters specific to each deck type. These alternative deck systems include an aluminum bridge deck system and a glass fiber reinforced plastic (GFRP) deck system. All three alternatives and the original steel grid deck system were evaluated based on the global responses of the moveable bridge, and the advantages and disadvantages of adopting the UHP-FRC deck system are quantified.
