Download or read book An Integral Abutment Bridge with Precast Concrete Piles written by Robert Emil Abendroth and published by . This book was released on 2007 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the details of the first integral abutment bridge in the state of Iowa that utilized precast, prestressed concrete piles in the abutment. The bridge, which was constructed in Tama County in 2000, consists of a 110 ft. long, 30 ft. wide, single-span PC girder superstructure with a left-side-ahead 20 degree skew angle. The bridge was instrumented with a variety of strain gages, displacement sensors, and thermocouples to monitor and help in the assessment of structural behavior. The results of this monitoring are presented, and recommendations are made for future application of precast, prestressed concrete piles in integral abutment bridges.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Tennessee Department of Transportation (TDOT) has designed and built integral abutment bridges with prestressed concrete piles for many years. A product of constructing integral bridge abutments is that the piles supporting the structure are exposed to lateral deflections, which come mainly from thermal expansion and contraction of the bridge structure. TDOT funded a project in which the University of Tennessee, Knoxville investigated the effects of the lateral displacement of four 14 inch square prestressed concrete piles that were driven into virgin clay soil. The tests involved full scale lateral loading each of the four prestressed piles; each pile supported a simulated integral bridge abutment. After each pile was driven into the ground, the model abutment and a "pulling slab" were cast on top of the pile. Leaving one foot of pile exposed between the abutment and the ground, University personnel instrumented each pile with strain gages on that exposed surface. The tests then included a basic testing regime of lateral displacements that depended on incremental displacement and time rate of loading. During the tests, moments, deflections, and shears were recorded at the pile-abutment interface. LPILE is a program that uses a finite difference analysis to calculate the behavior of a pile. While the piles in the field were not instrumented below the surface of the ground, LPILE was used to develop moment versus depth diagrams. Also the analysis evaluated shear and displacement versus depth graphs. LPILE was evaluated on its ability to predict the values measured at the pile abutment interface in the field tests and the consistency with which LPILE located maximum values and inflection points. The LPILE analyses were crude approximations of measured values.

Book Synopsis Long Term Behavior of Integral Abutment Bridges by : Robert J. Frosch
Download or read book Long Term Behavior of Integral Abutment Bridges written by Robert J. Frosch and published by . This book was released on 2011 with total page 3 pages. 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.

Book Synopsis Behavior of Semi-integral Abutment Bridge with Turn-back Wingwalls Supported on Drilled Shafts by : Safiya Ahmed
Download or read book Behavior of Semi-integral Abutment Bridge with Turn-back Wingwalls Supported on Drilled Shafts written by Safiya Ahmed and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semi-integral abutment bridges are integral abutment bridges with a flexible interface at the abutment to reduce the force transferred to the foundation. Wingwalls in abutment and semi-integral abutment bridges are designed as retaining walls to avoid the sliding of the backfill soil behind the bridge abutments and roadways. Using turn-back wingwalls that are parallel to the bridge diaphragm can provide support for the parapets and minimize the total longitudinal pressure on the abutments. These walls are subjected to axial forces and bending moments due to the thermal movements. These forces can affect the orientation and the connection details of the wingwalls, which could cause cracks in the wingwalls. Despite several studies on integral abutment bridges, there are no studies that combined the behavior of the drilled shafts, footings, abutment walls, and the turnback wingwalls of semi-integral abutment bridges. The long-term performance of a semi-integral abutment bridge with turn-back wingwalls supported on drilled shafts in Ohio was investigated in this doctorate study by instrumenting five drilled shafts, footing, the forward abutment wall, and one of the wingwalls during construction. Strain and temperature were collected in 2017, 2018, and 2019. It was found that the seasonal and daily temperature changes have a significant effect on the changes in the strain in the substructure. The behavior of the abutment wall significantly affects the behavior of the wingwall, footing, and drilled shafts. It was also noticed that the behavior of the abutment was irreversible, and the top of the abutment wall and the top of the drilled shaft induced higher strain than the bottom. Cracks were noticed at the front face of the abutment wall and wingwall, and these cracks tended to close as the air temperature decreased and open as the air temperature increased. The extremely cold weather conditions induced tensile strain higher than the allowable strain at the top corner of the front face of the abutment wall and the rear face of the wingwall. Finite element results were compared with the field data, and the behavior of the substructure was achieved by the model. Parametric studies were conducted on the bridge substructure with different wingwall types and soil backfill. The results showed lower stiffness of soil backfill induces higher stresses in the bridge substructure. Moreover, inline wingwalls induce the highest thermal stresses in the substructure, while flared wingwalls induce the lowest thermal stress compared to the other types of wingwalls.
Book Synopsis The Behavior of Integral Abutment Bridges by : Sami Arsoy
Download or read book The Behavior of Integral Abutment Bridges written by Sami Arsoy and published by . This book was released on 1999 with total page 33 pages. Available in PDF, EPUB and Kindle. 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.

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: 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.
