This book was released on 2014 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research program develops and validates structural design guidelines and details for concrete bridge decks with corrosion-resistant reinforcing (CRR) bars. A two-phase experimental program was conducted where a control test set consistent with a typical Virginia Department of Transportation bridge deck design using Grade 60 steel (ASTM A615, f [subscript] y = 60 ksi) and epoxy-coated reinforcing steel was compared to deck slab specimens where Grade 60 is replaced with CRR bars. The experimental program was designed to evaluate how flexural performance at service and ultimate limit states are affected by a one-to-one replacement of Grade 60 with CRR bars, a reduction of concrete clear cover, and a reduction in rebar size. Structural analysis models were developed using Response 2000 in order to predict the CRR bridge deck moment-curvature and the moment-crack width relationships. Experimental trends proved to be consistent with the analytical results demonstrating the viability of Response 2000 as a design tool for reinforced concrete with high-strength and nonmetallic rebar without a defined yield plateau. For reduced bar size and clear cover (2.00 in instead 2.50 in), ASTM A1035 and UNS S32304 specimens proved to have similar deformability ratios and crack widths that comply with current AASHTO requirements, with as much as 36% less steel.

This book was released on 2017 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recently developed corrosion-resistant reinforcing structural design guidelines were used to design, construct, and assess a reinforced concrete bridge deck with high-strength ASTM A1035 CS steel bars. The bridge replacement is located along the North Scenic Highway over the Wolf Creek in Bland County, Virginia. The bridge deck design used the higher yield stress available from ASTM A1035 CS steel to replace No. 5 bars with No. 4 bars that saved 23% by weight of steel in the deck and reduced reinforcement bar congestion, especially near the traffic barrier-bridge deck splice. The material cost savings was also 23% compared to a standard Virginia Department of Transportation bridge deck since the bars were bid as a cost per unit weight. The Wolf Creek Bridge deck surface (i.e., cracks, slope, and surface profile) was documented using an automated computer vision system assembled with off-the-shelf cameras that accurately surveyed the bridge deck in less than 10 minutes, providing a high resolution 3D digital state model before and after the bridge was opened to traffic. The bridge deck is in excellent condition after 2 months in service, with only one crack of 0.004 in observed near a construction joint. The study concluded that concrete bridge decks can be designed with No. 4 bars and constructed considering the structural benefits of gradually yielding, high-strength ASTM A1035 CS reinforcement bars with satisfactory in-service performance and some cost savings.

Book Synopsis Design of Reinforced Concrete Bridge Decks Under Moving Loads by : PC. Perdikaris
Download or read book Design of Reinforced Concrete Bridge Decks Under Moving Loads written by PC. Perdikaris and published by . This book was released on 1998 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents design recommendations of non-composite reinforced concrete bridge decks subjected to fatigue due to moving loads. These recommendations are based on test results of 1/3- and 1/6.6- scale physical models of a full-scale 21.6-cm (8.5 in.) thick and 15.24-m (50-ft) long simply supported non-composite reinforced concrete deck. Concrete bridge decks should be designed to transfer the load in a two-way action. Experimental results show that the two-way slab action in the decks changes to a one-way action (transverse direction) as fatigue damage due to a moving wheel-load accumulates. It is recommended to adopt an isotropic steel reinforcing pattern. An isotropic reinforcing pattern with a steel ratio of 0.3 % (each top and bottom layer) in each direction appears to be adequate. A similar reinforcing amount and pattern is required by the Ontario bridge design Code. The required steel content is therefore reduced resulting in substantial savings in the bridge deck construction costs and improving the corrosion resistance in decks, especially in the presence of deicing chemicals. It appears that flexural cracking in the deck and bond failure at the steel-concrete interface are necessary and sufficient conditions for deck failure under traffic loads. It is, thus, highly desirable to preclude or at least limit cracking and maximize the bond strength of the steel rebars.

Cremona and Poulin propose an assessment procedure for existing bridges. Kallias et al. develop a framework for the performance assessment of metallic bridges under atmospheric exposure by integrating coating deterioration and corrosion modelling. Soriano et al. employ a simplified approach to estimate the maximum traffic load effect on a highway bridge and compare the results with other approaches based on on-site weigh-in-motion data. Akiyama et al. propose a method for reliability-based durability design and service life assessment of reinforced concrete deck slab of jetty structures. Chen et al. propose a meso-scale model to simulate the uniform and pitting corrosion of rebar in concrete and to obtain the crack patterns of the concrete with different rebar arrangements. Ruan et al. present a traffic load model for long span multi-pylon cable- stayed bridges. Khuc and Catbas implement a non-target vision- based method for the measurement of both static and dynamic displacements time histories. Finally, Cruz presents the career of the outstanding bridge engineer Edgar Cardoso in the fields of bridge design and experimental analysis. The book serves as a valuable reference to all concerned with bridge structure and infrastructure systems, including students, researchers, engineers, consultants and contractors from all areas sections of bridge engineering.

Download or read book Evaluation of the Empirical Deck Design for Vehicular Bridges written by Georges El-Gharib and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This research evaluated the feasibility of the empirical design method for reinforced concrete bridge decks for the Florida Department of Transportation [FDOT]. There are currently three methods used for deck design: empirical method, traditional method and finite element method. This research investigated and compared the steel reinforcement ratios and the stress developed in the reinforcing steel for the three different methods of deck design. This study included analysis of 15 bridge models that met the FDOT standards. The main beams were designed and load rated using commercial software to obtain live load deflections. The bridges were checked to verify that they met the empirical method conditions based on the FDOT Structures Design Guidelines-- January 2009. The reinforced concrete decks were designed using the traditional design method. Then the bridges were analyzed using three-dimensional linear finite element models with moving live loads. The reinforced concrete decks were designed using dead load moment, live load moment, and future wearing surface moment obtained from the finite element models. The required reinforcing steel ratio obtained from the finite element method was compared to the required reinforcing steel ratio obtained from traditional design method and the empirical design method. Based on the type of beams, deck thicknesses, method of analysis, and other assumptions used in this study, in most cases the required reinforcing steel obtained from the finite element design is closer to that obtained from the empirical design method than that obtained from the traditional design method. It is recommended that the reinforcing steel ratio obtained from the empirical design method be used with increased deck thicknesses to control cracking in the bridge decks interior bays.

Available in PDF, EPUB and Kindle. Book excerpt: High-performance (HP) steel reinforcing bars are characterized by their high tensile strength and enhanced corrosion resistance in comparison to conventional ASTM A 615 Grade 60 steel. Use of HP steel in concrete bridges could lead to potential savings by reducing the amount of steel required based on its higher strength characteristics and expanding the service life of bridges due to its enhanced corrosion resistance. A commercially available steel know Micro-Composite Multi-Structural Formable (MMFX) steel which is conforming to ASTM A 1035, was selected for this study because of its high tensile strength and enhanced corrosion resistance. Comprehensive experimental and analytical programs were carried out to evaluate the mechanical properties of the HP steel bars, its bond characteristics, and the behavior of concrete bridge decks reinforced with HP steel. Research findings showed that HP steel used in this study exhibited much higher tensile strength than that of conventional Grade 60. In addition, the HP steel bars had much lower corrosion rate than Grade 60 bars. Bending HP steel bars reduce its ultimate strength and strain by 6 and 70 percent, respectively. However, when HP steel bent bars are bonded to concrete they develop their full stress-strain capacity. Bond test results indicated that a stress level up to 90 ksi can be developed in #8 HP steel bars without the use of transverse reinforcement. The use of transverse reinforcement increases the bond strength of HP steel reinforcing bars, consequently reaching stress levels in the bars up to 150 ksi. When possible, it is recommended to use a minimum amount of transverse reinforcement to confine spliced bars to ensure ductile behavior and provide warning prior to failure. Direct replacement of Grade 60 with HP steel bars in bridge decks is a conservative approach. However, reducing the amount of HP steel by 33 percent does not impair the ultimate-load carrying capacity or alter the serviceability behavior o.
