This is especially true in cold regions like Alaska, where you face a very short summer season. The speed of construction can be expedited by connections. As there are advantages in connections there are also disadvantages. One of the primary advantages of the connectors is that it makes the load transfer mechanism very efficient. However everything comes for a price. Maintenance of connections is very difficult. Routine inspections are to be made to ensure proper functioning of the system. This becomes a very important factor in Alaska where extreme winter conditions exists. Another issue is that the current connector design is based on an empirical approach. A rational design method is needed. In this study an effort has been made to find the presence of ISD on the live load distribution factor for single lane loading. Using ABAQUS CAE, 3D finite element (FE) models have been developed and analyzed with different parameters. By varying the parameters, different distribution factors corresponding to the reaction, strains (flexure and shear) as well as the forces originating from the connectors are evaluated and compared. This paper provides a basis for future connector design"--Leave iv.

Book Synopsis Finite Element Analysis of Prestressed Concrete Structures Using Post-Tensioning Steel by : Yu Huang
Download or read book Finite Element Analysis of Prestressed Concrete Structures Using Post-Tensioning Steel written by Yu Huang and published by Cambridge Scholars Publishing. This book was released on 2020-05-28 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book details the theory and applications of finite element (FE) modeling of post-tensioned (PT) concrete structures, and provides the updated MATLAB code (as of 2019). The challenge of modeling PT prestressed concrete structures lies in the treatment of the interface between the concrete and prestressing tendons. Using MATLAB, this study develops an innovative nonlinear FE formulation which incorporates contact techniques and engineering elements to considerably reduce the need of computational power. This FE formulation has the ability to simulate different PT frame systems with fully bonded, fully unbonded or partially bonded tendons, as well as actual sliding behavior and frictional effects in the tendons. It also allows for the accurate simulation of anchor seating loss.

Book Synopsis Finite Element Modeling and Analysis of Reinforced-concrete Bridge Decks by :
Download or read book Finite Element Modeling and Analysis of Reinforced-concrete Bridge Decks written by and published by . This book was released on 2000 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite its long history, the finite element method continues to be the predominant strategy employed by engineers to conduct structural analysis. A reliable method is needed for analyzing structures made of reinforced concrete, a complex but common ingredient in many bridges in Virginia. As an effective alternative to extensive experimentation, this study was implemented to evaluate the plausibility of finite element analysis of reinforced-concrete bridge decks. Analytical evaluations were performed with the commercial, general-purpose finite element code ABAQUS, which can effectively depict the nonlinear behavior of concrete. It also has the unique capability of describing the behavior of reinforcing bars independently of the concrete material. Three-dimensional finite element models were developed to determine the overall structural response of several reinforced-concrete systems. Biaxial strain distribution through the element thickness, longitudinal normal girder strains, and displacements were predicted with reasonable accuracy. The accuracy of the model was verified with hand calculations or response data acquired from laboratory testing.
Book Synopsis Strength and Stability of Prestressed Concrete Through-girder Pedestrian Bridges Subjected to Vehicular Impact by : Eray Baran
Download or read book Strength and Stability of Prestressed Concrete Through-girder Pedestrian Bridges Subjected to Vehicular Impact written by Eray Baran and published by . This book was released on 2007 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two issues regarding the prestressed concrete through-girder pedestrian bridge system are investigated. The first issue concerns the ductility of prestressed concrete girders in these bridges because the section that is typically used may be considered to be over-reinforced according to AASHTO LRFD Bridge Specifications. Response of the section, including neutral axis location, strand stress at ultimate capacity, and moment capacity, predicted by AASHTO Standard and AASHTO LRFD Specifications are compared with the sectional response determined from nonlinear strain compatibility analyses. Modifications are proposed to the AASHTO LRFD procedure to rectify the errors in predicting sectional response. The second issue that was investigated concerns the strength and stability of prestressed concrete through-girder pedestrian bridges when subjected to impact by over-height vehicles. Three-dimensional finite element models of entire bridges and subassemblages were used to evaluate the strength, stiffness, and ductility characteristics of the bridge system and connection details. Accurate representation of the bridge details in the finite element models were assured by utilizing experimentally determined load-deformation characteristics for the connections. Results showed that significant improvements in the lateral load-deflection behavior of the bridge system could be obtained by implementing alternate connection schemes, and that concrete side-walls should be provided at girder ends.

Book Synopsis 3-D Finite Element Modeling in OpenSees for Bridge Live-load Girder Distribution Factors by : Luke A. Scoggins
Download or read book 3-D Finite Element Modeling in OpenSees for Bridge Live-load Girder Distribution Factors written by Luke A. Scoggins and published by . This book was released on 2008 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: A generalized, three-dimensional, finite element bridge model was created in order to efficiently and accurately assess live-load girder distribution factors for a variety of bridge types. This model shortens the time required by bridge analysts to develop individual finite element models for bridges of varying geometries. The creation of the generalized bridge model was based on previous modeling techniques successfully implemented and tested by different researchers. The proposed modeling scheme utilizes a combination of shell elements for the deck, frame elements for the girders, and rigid beam links connecting these two element types. The versatility of the finite element program, OpenSees, allowed for the creation of this generalized bridge model. The Tcl scripting language, used to define the analysis for implementation in OpenSees, enhances the capabilities of generalizing the truck types and loading procedures for analysis. The generalized finite element bridge model developed for use in OpenSees was validated through comparison to two bridges analyzed by field testing and finite element modeling in a previous research study. The girder distribution factors of these conventionally reinforced concrete bridges were determined with the generalized bridge model and compared to the results of the previous research and to factors determined with the AASHTO LRFD (2003) specification. The results determined with the generalized model compared well with the results of the previous study and effectively validated the model. Factors evaluated with AASHTO LRFD (2003) were shown to be generally conservative. The generalized bridge model was found to accurately and efficiently evaluate live-load girder distribution factors and could prove useful to economically rate a large number of bridges.
