Finite Element Analysis Of The Wolf Creek Multispan Curved Girder Bridge by John C. Lydzinski


Original Title: Finite Element Analysis Of The Wolf Creek Multispan Curved Girder Bridge

The use of curved girder bridges in highway construction has grown steadily during the last 40 years. Today, roughly 25% of newly constructed bridges have a curved alignment. Curved girder bridges have numerous complicating geometric features that distinguish them from bridges on a straight alignment. Most notable of these features is that longitudinal bending and torsion do not decouple. Although considerable research has been conducted into curved girder bridges, and many of the fundamental aspects of girder and plate behavior have been explored, further research into the behavior and modeling of these bridges as a whole is warranted. This study developed two finite element models for the Wolf Creek Bridge, a four-plate girder bridge located in Bland County, Virginia. Both models were constructed using plate elements in ANSYS, which permits both beam and plate behavior of the girders to be reproduced. A series of convergence studies were conducted to validate the level of discretization employed in the final model. The first model employs a rigid pier assumption that is common to many design studies. A large finite element model of the bridge piers was constructed to estimate the actual pier stiffness and dynamic characteristics. The pier natural frequencies were found to be in the same range as the lower frequencies, indicating that coupling of pier and superstructure motion is important. A simplified "frame-type" pier model was constructed to approximate the pier stiffness and mass distribution with many fewer degrees of freedom than the original pier model, and this simplified model was introduced into the superstructure model. The resulting bridge model has significantly different natural frequencies and mode shapes than the original rigid pier model. Differences are particularly noticeable in the combined vertical bending/torsion modes, suggesting that accurate models of curved girder bridges should include pier flexibility. The model has been retained for use as a numerical test bed to compare with field vibration data and for subsequent studies on live load distribution in curved girder bridges. The study recommends consideration of the use of the finite element method as an analysis tool in the design of curved girder bridge structures and the incorporation of pier flexibility in the analysis.

Analysis And Design Of Plated Structures by N E Shanmugam


Original Title: Analysis And Design Of Plated Structures

Steel and other types of plated structures are used in a variety of applications from aircrafts to ships and offshore platforms to bridges, power plants and cranes. A key issue in the use of these structures is their stability behaviour under compressive stress. Analysis and design of plated structures reviews the wealth of research in this important area and its implications for design, safety and maintenance. The book considers the various types of buckling that plated structures are likely to encounter. Chapters also review buckling in a range of materials from steel to differing types of composite. The book also discusses the behaviour of differing types of components used in steel-plated structures. These components include steel beams and columns as well as curved, stiffened, corrugated, laminated and other types of plate design. With its distinguished editors and international team of contributors, Analysis and design of plated structures is a useful standard reference for civil engineers involved in the design of plated structures. Discusses the behaviour of steel and other plated structures when under stress Extensive coverage of the key research in this important area Compiled by an international team of distinguished contributors
