This book was released on 2013-05-15 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The primary objective of this chapter is first to introduce and demonstrate the application of thermoplastic (woven glass reinforced polypropylene) in the design of modular fiber-reinforced bridge decks, and next the development of jackets for confining concrete columns against compression and impact loading. The design concept and manufacturing processes of the thermoplastic bridge deck composite structural system are presented by recognizing the structural demands required to support highway traffic. Then the results of the small-scale static cylinder tests and the impact tests of concrete columns are presented, demonstrating that thermoplastic reinforcement jackets act to restrain the lateral expansion of the concrete that accompanies the onset of crushing, maintaining the integrity of the core concrete, and enabling much higher compression strains (compared to CFRP composite wraps) to be sustained by the compression zone before failure occurs.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid deterioration of civil infrastructure has created one of the major challenges facing the construction industry. In recent years, fiber reinforced polymers (FRP) have emerged as a potential solution to the tribulations associated with deficient bridge decks. The main objective of the proposed research is to adapt the 3-D orthogonal 3WeavingTM process to develop an innovative completely woven fiber reinforced polymeric bridge deck. The research accomplished fabricating a unique 3WeavingTM loom capable of weaving an E-glass preform which 'puffs out' into an open cell truss-like structure aimed to overcome each the weaknesses of its predecessors. The project succeeded in providing fiber reinforcement through the connection of the truss core components with the outer composite deck skins. The loom provided continuous fiber reinforcement through these top and bottom skins. And the innovative fiber architecture provided inplane fiber reinforcement in each of the structural components. Two 5' long by 15' wide deck preforms were produced: the first 1 1⁄2 thick and the second 3' thick. In addition, a 2' long by 12' wide by 1 1⁄2 thick non-truss composite deck was produced for comparison. The truss oriented decks utilized triangular cut shafts of Balsa as core inserts, and the non-truss deck maintained a rectangular block of Balsa core; each deck was infused with an epoxy resin; and concrete was cast atop. Each of the decks was tested for stiffness and strength in three-point bend. The stiffness tests comprised loading and unloading the deck in 2 kip increments up to 22 kips and using linear regression analysis to ascertain any degradation in stiffness. The strength tests consisted of loading the deck until failure. The testing exemplified the importance of the attachment of the core structural components to the outer composite deck skins and demonstrated a resistance of delamination of the core to the outer skins and the outer skins to themselves.

Book Synopsis Ultra-high Performance Fiber Reinforced Concrete in Bridge Deck Applications by : Jun Xia
Download or read book Ultra-high Performance Fiber Reinforced Concrete in Bridge Deck Applications written by Jun Xia and published by . This book was released on 2011 with total page 145 pages. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Throughout the United States including New York, many reinforced concrete bridges on county and state highway systems have deteriorated to the certain degree that structural strengthening is necessary to extend their service life. Fiber reinforced polymer (FRP) composite systems appeared to be one of the options to address the issues of cost-effective load-rating improvement. Recently, an FRP deck has been installed on a state highway, located in New York State, as an experimental project. This paper describes multi-step linear static analyses that were conducted using the finite element method to study the possible failure mechanisms of the deck-superstructure system. Finite element model was verified using the load tests of the bridge deck. Furthermore, the thermal behavior of the FRP deck was investigated and presented in this paper. Analytical results reveal several potential failure mechanisms for the FRP deck and truss bridge system.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of prefabricated superstructure elements in bridge construction reduces on-site construction time, improves work-zone safety, and can reduce overall project costs. For prefabricated elements to be used efficiently for accelerated bridge construction (ABC), the precast components, such as deck panels or decked-bulb tees, must be connected quickly on-site, ideally using as little additional material as possible. The use of fiber-reinforced polymer concrete (FRPC) was explored as a closure pour material for bridges to connect adjacent precast superstructure elements. Polymer concretes have been used successfully as a non-structural overlay material in transportation systems for many decades. With the addition of fibers, FRPC displays levels of two critical characteristics, bond and tension strength, that are comparable to other alternatives, such as ultra-high performance concrete (UHPC). While UHPC may still provide the best solution in many instances, FRPC has the advantage of requiring shorter closure windows (approximately 4 hours versus 72 hours for UHPC) due to the very rapid strength gain of the polymer, which could be ideal for overnight construction or rehabilitation projects. The bond and mechanical properties of FRPC were determined at several temperatures, spanning the range of typical service conditions in western Washington State. Tests were completed measuring the compressive, flexural, and bond strength of FRPC. Then, a central composite rotatable experimental design was utilized to explore the impact of splice length, side cover, bar size, and temperature on bar stress in non-contact splice specimens. The test setup was similar to that completed by the Federal Highway Administration (FHWA) with UHPC. The results of the testing program indicate that FRPC exhibits significant variation in mechanical properties with temperature, roughly -0.6 %/°F; the development of early compressive, flexure, and bond strengths were very similar, reaching roughly 70% of their 7-day values in 4 hours; and peak bar stresses in non-contact lap splices embedded in FRPC were comparable to UHPC for the embedded lengths tested. Based on the testing results, example joint configurations for connecting precast superstructure elements were developed, enabling the comparison of FRPC with alternative closure pour materials for future ABC projects.
