This book was released on 2011-08-15 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integral abutment (IA) construction has become the preferred method over conventional construction for use with typical highway bridges. However, the use of these structures is limited due to state mandated length and skew limitations. To expand their applicability, studies were implemented to define limitations supported by rational analysis rather than simply engineering judgment. Previous research investigations have resulted in larger length limits and an overall better understanding of these structures. However, questions still remain regarding IA behavior; specifically questions regarding long-term behavior and effects of skew. To better define the behavior of these structures, a study was implemented to specifically investigate the long term behavior of IA bridges. First, a field monitoring program was implemented to observe and understand the in-service behavior of three integral abutment bridges. The results of the field investigation were used to develop and calibrate analytical models that adequately capture the long-term behavior. Second, a single-span, quarter-scale integral abutment bridge was constructed and tested to provide insight on the behavior of highly skewed structures. From the acquired knowledge from both the field and laboratory investigations, a parametric analysis was conducted to characterize the effects of a broad range of parameters on the behavior of integral abutment bridges. This study develops an improved understanding of the overall behavior of IA bridges. Based on the results of this study, modified length and skew limitations for integral abutment bridge are proposed. In addition, modeling recommendations and guidelines have been developed to aid designers and facilitate the increased use of integral abutment bridges.

Available in PDF, EPUB and Kindle. Book excerpt: Integral abutment bridges, a type of jointless bridge, are the construction option of choice when designing highway bridges in many parts of the country. Rather than providing an expansion joint to separate the substructure from the superstructure to account to volumetric strains, an integral abutment bridge is constructed so the superstructure and substructure are continuous. The abutment is supported by a single row of piles which must account for the longitudinal movement previously accommodated by the joints. The primary advantage of an integral abutment bridge is that it is jointless (expansion joints are eliminated) and thus reduces both upfront and overall life-cycle costs. In addition to other benefits provided by integral construction, the reduction in overall cost has led to INDOT requiring all new structures within certain geometric limitation be integral. These geometric limitations, traditionally based on engineering judgment, have been modified over time based as investigations have revealed more about the behavior of integral abutment bridges. While there has been a considerable amount of research and investigation conducted on the behavior of integral abutment bridges, information is limited on both long-term behavior and the effects of highly skewed structures. Because there is a great desire for the application of these structures to be expanded, this research serves to expand the understanding of the behavior of integral abutment structures. Additionally, updated geometric limitations are recommended along with design recommendations and recommended analysis procedures for properly modeling integral abutment behavior.

Available in PDF, EPUB and Kindle. Book excerpt: This project investigated the seasonal behavior of integral abutment bridges through field monitoring and finite element modeling (FEM). The Orange-Wendell Bridge was used as a case study for the project. The structure was instrumented with 85 gages measuring bridge movements and forces (temperature gages, joint meters, tilt meters, strain gages, earth pressure cells, thermistors and four inclinometer casings for manual readings). Instruments were monitored by the University of Massachusetts at Amherst from January 2002 through December 2004. Both 2-D and 3-D FEM of the bridge were developed using GTSTRUDL and calibrated to the field data. Parametric FEM was performed to evaluate the influence of soil properties and construction practices on bridge behavior.

Book excerpt: This report presents findings of a literature review, a field trip, and a finite element analysis pertaining to integral bridges. The purpose of the report is to identify problems and uncertainties, and to gain insight into the interactions between the foundation piles, the integral abutment, and the surrounding ground. The field trip included visits to six bridges arranged by Mr. Park Thompson from the Staunton district. Pertinent literature is reviewed and findings are presented. Important factors identified on the basis of this review are settlement of the approach fill, loads on the abutment piles, the nature of the abutment displacements and the associated earth pressure distribution, secondary loads on the superstructure, and soil structure interaction effects. The causes of approach fill settlement and possible mitigation techniques are discussed. Recommendations for improving the performance of integral bridges are included, and actions for improvement of integral bridge behavior are suggested.

Available in PDF, EPUB and Kindle. Book excerpt: As a result of abutment spalling on the integral abutment bridge over 400 South Street in Salt Lake City, Utah, the Utah Department of Transportation (UDOT) instigated research measures to better understand the behavior of integral abutment bridges. The bridge was instrumented with survey targets and monitored each month for one year. The monthly surveys were also supplemented by a day-long survey. Measurements of temperature change and span length were obtained and used to show general trends in the movement of the 400 South Street Bridge.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project was to revise and make more accurate integral abutment bridge design criteria based on observed structural behavior and results of numerical parametric studies. Observed behaviors were on the basis of field monitoring conducted at 4 integral abutment bridge sites and a weather station utilizing previously installed instrumentation and data acquisition systems. Integral abutment bridge engineering data were continuously collected over the entire contract period at bridges 109, 203, 211, and 222 and compiled, processed and evaluated. Numerical parametric studies were conducted on the basis of 2D and 3D finite element models, developed and calibrated to the observed integral abutment behavior, in order to evaluate the field performance of integral abutments and establish the range of potential applications for integral abutment bridge construction in Pennsylvania.
