Available in PDF, EPUB and Kindle. Book excerpt: The usage of Ultra High Strength Fiber Reinforced Concrete (UHSFRC) with higher compressive strength (15,000-29,000 psi) in construction industry has been increasing worldwide. UHSFRC is also known as reactive powder concrete (RPC) which exhibits excellent durability and mechanical properties. This is one of the latest and emerging topics in the concrete technology. Structural elements cast with UHPC can carry larger loads and exhibit energy absorption capacity with smaller sections.The high compressive strength, higher tensile strength along with almost negligible water and chloride permeability therefore better durability of this new concrete material makes it UHSFRC. The basic principle in UHSFRC is to make the cement matrix as dense as possible, by reducing the micro cracks and capillary pores in the concrete and also to make a dense transition zone between cement matrix and aggregates. These special properties of concrete can be achieved by eliminating the coarse aggregates and replacing them with quartz sand of maximum size of 600 microns.The possibility of achieving high strength, durability, and ductility concrete encourages engineers to use this innovative material in many applications such as nuclear waste containment structures, high rise structures, long span bridges, walkways and in many more applications.ivConcrete (UHSFRC) using materials that are available locally are always economical since the patented products are very expensive and the materials such as silica sand and quartz powder are not readily available. The research also includes use of recognized mineral admixtures, natural river sand, steel fibers, and superplasticizers (Sika Viscocrete 2100 - 3% by weight of cement, Melflux 4930 - 1% by weight of cementitious material) without using any coarser aggregates, and an optimum dosage of silica fume was 15 % by weight of the cement.The structural integrity and durability of concrete used in shear keys is vital for the performance of bridges constructed using precast concrete components. The use of UHPC in the construction of shear keys can be a good solution for achieving long lasting bridge systems. The evaluation of UHPC shear key was conducted by connecting the precast concrete girders together via shear key. The test specimen was a simply supported beam with the shear key connection at mid span.The fresh and hardened mechanical properties of the UHSFRC were studied such as workability of the mix, compression test on cubes, split tensile test on cylinders, flexural tensile test for both reinforced and unreinforced concrete beams, rebar pull-out tests, impact test on panels and testing for shear keys.Two different curing practices were used in this work: Moist Curing (MC) and Heat Curing (HC). Two different types of cements used were ASTM Type I and Type III cements. Type I cement is commonly used in all the construction works whereas Type III cement is used in special applications where early high strengths are required. Both the cements are used for the comparative study, keeping all the proportions constant.vCompressive strength of 21,500 psi was achieved with concrete made of type III cement using moist curing practice. Split tensile strength of 2,300 psi and flexural strength of 3,300 psi were gained using Type III cement and moist curing practice. Highest compressive strength of 28,150 psi is achieved using heat curing practice. It was found that heat curing practice may be artificially inflating the compressive strength. The split tensile strength, and flexural strength results of heat-cured specimens have lower strength compared to moist cured specimens. The moment capacity of the fiber reinforced concrete is twice than the conventional concrete, due to the denser microstructure, absence of coarse aggregates, and cement silica reaction. Potential application of UHSFRC in shear keys of adjacent box beam girder bridges was demonstrated on small joint test specimens with sand blasted surface. It is concluded that the use of the mix design developed in this study for UHSFRC is feasible for such box beam bridges.

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.

Download or read book Cable Supported Bridges written by Niels J. Gimsing and published by John Wiley & Sons. This book was released on 2011-12-30 with total page 760 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fourteen years on from its last edition, Cable Supported Bridges: Concept and Design, Third Edition, has been significantly updated with new material and brand new imagery throughout. Since the appearance of the second edition, the focus on the dynamic response of cable supported bridges has increased, and this development is recognised with two new chapters, covering bridge aerodynamics and other dynamic topics such as pedestrian-induced vibrations and bridge monitoring. This book concentrates on the synthesis of cable supported bridges, suspension as well as cable stayed, covering both design and construction aspects. The emphasis is on the conceptual design phase where the main features of the bridge will be determined. Based on comparative analyses with relatively simple mathematical expressions, the different structural forms are quantified and preliminary optimization demonstrated. This provides a first estimate on dimensions of the main load carrying elements to give in an initial input for mathematical computer models used in the detailed design phase. Key features: Describes evolution and trends within the design and construction of cable supported bridges Describes the response of structures to dynamic actions that have attracted growing attention in recent years Highlights features of the different structural components and their interaction in the entire structural system Presents simple mathematical expressions to give a first estimate on dimensions of the load carrying elements to be used in an initial computer input This comprehensive coverage of the design and construction of cable supported bridges provides an invaluable, tried and tested resource for academics and engineers.
