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.

Book excerpt: Since the service life of concrete bridge decks designed by traditional procedures is often shorter than desired, their ability to withstand constant and heavy use in a variety of operating environments is of major concern. In this project, the relative performance of three bridge decks constructed with different concretes and reinforcing steel configurations was studied to help determine which deck offers the best performance over time. To achieve this objective, an array of strain and temperature instrumentation was embedded in each of the bridge decks prior to placing the deck concrete. The decks were tested under controlled live loads to characterize their structural behavior. The first set of such tests was performed immediately after the bridge decks were completed, and the second was conducted two years later. The long term performance of the three decks under environmental loads (notably, changes in temperature) was studied by continuously monitoring selected strain gages in each bridge, and by conducting periodic visual distress surveys and corrosion tests. In the data collected and analyzed from the live load tests and environmental response monitoring of the three decks, only subtle behavioral differences have been observed. While some aspects of the response have been found to statistically differ between bridges and over time, the significance of these differences remains uncertain, as the bridges are relatively young, and they only exhibit nominal signs of distress. The significance of these differences may become clear in the future, if substantial differences in deck durability and performance emerge over time. The visual distress surveys have found that the majority of the cracking that has occurred in the decks is near the integral abutments and that the Empirical deck had the most extensive cracking in this regard. The analysis presented herein generally serves as a baseline for the relative condition of the three bridges before prolonged demands from traffic and the environment. Should a follow-on project be initiated, data obtained from continued long-term monitoring and live load testing will likely provide a more complete body of evidence from which to ascertain which deck design offers superior performance. Relative to cost, initial expense for each deck was similar, thus the relative cost-to-benefit for the decks will be dependent on the service life that they offer.

This book was released on 2002 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: A literature review concerning the objectives of the project was completed. A significant number of published papers, reports, etc., were examined to determine the effectiveness of full depth precast panels for bridge deck replacement. A detailed description of the experimental methodology was developed which includes design and fabrication of the panels and assembly of the bridge. The design and construction process was carried out in cooperation with the project Technical Review Panel. The major components of the bridge deck system were investigated. This includes the transverse joints and the different materials within the joint as well as composite action. The materials investigated within the joint were polymer concrete, non-shrink grout, and set-45 for the transverse joint. The transverse joints were subjected to direct shear tests, direct tension tests, and flexure tests. These tests exhibited the excellent behavior of the system in terms of strength and failure modes. Shear key tests were also conducted. The shear connection study focused on investigating the composite behavior of the system based on varying the number of shear studs within a respective pocket as well as varying the number of pockets within a respective panel. The results indicated that this shear connection is extremely efficient in rendering the system under full composite action. Finite element analysis was conducted to determine the behavior of the shear connection prior to initiation of the actual full scale tests. In addition, finite element analysis was also performed with respect to the transverse joint tests in an effort to determine the behavior of the joints prior to actual testing. The most significant phase of the project was testing a full-scale model. The bridge was assembled in accordance with the procedures developed as part of the study on full-depth precast panels and the results obtained through this research. The system proved its effectiveness in withstanding the applied loading that exceeded eight times the truck loading in addition to the maximum negative and positive moment application. Only hairline cracking was observed in the deck at the maximum applied load. Of most significance was the fact that full composite action was achieved between the precast panels and the steel supporting system, and the exceptional performance of the transverse joint between adjacent panels.

Download or read book Grillage Analogy in Bridge Deck Analysis written by C. S. Surana and published by Alpha Science Int'l Ltd.. This book was released on 1998 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the well established computer-aided method of grillage analogy as applied to analysis of bridge decks. The method, applicable to various types of bridge decks (such as slab bridges, T-beam bridges and box-girder bridges), can handle rigid or flexible support conditions, and right, skew or curved plan layouts.The procedure and recommendations for idealising the actual bridge decks and loadings into mathematical models are discussed. Two programs, given in ready-to-use form, along with descriptions of various subroutines, can analyse a variety of bridge decks accurately and obtain all the responses required in the design. Their uses are explained through worked-out examples. These programs, along with input-data and exhaustive output results of all the worked-out examples, are also available on a diskette and can be ordered seperately from the authors through the publisher. This will help those who do not want to type programs from the book and run into possible risk of errors.The book will be useful for the students, researchers, teachers, designers and consultants engaged in analysing, designing, vetting, tendering or constructing bridges.

This book was released on 2008-11-01 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transverse cracking of concrete bridge decks is problematic in numerous states. Cracking has been identified in the negative and positive moment regions of bridges and can appear shortly after opening the structure to live loads. To improve the service life of the bridge deck as well as decrease maintenance costs, changes to current construction practices in Indiana are being considered. A typical bridge deck was instrumented which incorporated the following: increased reinforcement amounts, decreasing reinforcement spacing, and high-performance, low-shrinkage concrete. The low shrinkage concrete was achieved using a ternary concrete mix. The objective of this research was to determine the performance, particularly in terms of transverse cracking and shrinkage, of a bridge incorporating design details meant to reduce cracking. Based on measurements from the bridge, it was determined that maximum tensile strains experienced in the concrete were not sufficient to initiate cracking. An on-site inspection was performed to confirm that cracking had not initiated. The data was analyzed and compared with the behavior of a similarly constructed bridge built with nearly identical reinforcing details, but with a more conventional concrete to evaluate the effect of the HPC. Based on this study, it was observed that full-depth transverse cracks did not occur in the structure and that the use of HPC lowered the magnitude of restrained shrinkage strains and resulting tensile stresses.
