Reports on results of a combined analytical and experimental investigation to improve the cyclic inelastic performance of welded steel, unreinforced flange moment connections for use in earthquake resistant construction. Issues such as the geometry and size of the weld access holes, the amount of inelastic panel zone deformation, the use of supplemental web fillet welds, the influence of continuity plates, and the effects of a concrete slabs are all studied as part of the investigation.

Title: Coupled Pressuremeter-Phicometer Analysis for Soil Exploration Author / Creator: Katzenbach, R.; Gutberlet, C.; Wachter, S.; American Society of Civil Engineers In: GEOTECHNICAL SPECIAL PUBLICATION, 175; 906-915; 7th, International symposium on field measurements in geomechanics: FMGM 2007 Publisher: American Society of Civil Engineers , Reston, Va. Year of publication: 2007 Size: 10 Pages
Knowing the safety factor for limit states such as plastic collapse, low cycle fatigue or ratcheting is always a major design consideration for civil and mechanical engineering structures that are subjected to loads.
Direct methods of limit or shakedown analysis that proceed to directly find the limit states offer a better alternative than exact time-stepping calculations as, on one hand, an exact loading history is scarcely known, and on the other they are much less time-consuming.
This book presents the state of the art on various topics concerning these methods, such as theoretical advances in limit and shakedown analysis, the development of relevant algorithms and computational procedures, sophisticated modeling of inelastic material behavior like hardening, non-associated flow rules, material damage and fatigue, contact and friction, homogenization and composites.

Full-Scale Testing and Foundation Design (Geotechnical Special Publication - GSP 227)
Author: Mohamad H. Hussein, K. Rainer Massarsch, Garland E. Likins, Robert D. Holtz | Size: 47 MB | Format:PDF | Quality:Unspecified | Publisher: ASCE | Year: 2012 | ISBN: 0784412081
Full-Scale Testing and Foundation Design, GSP 227, honors Bengt H. Fellenius, Dr.Tech., P.Eng., for his noteworthy efforts to advance foundation engineering research, design, construction, and testing practices. From the beginning in Sweden of his 50-year career as a geotechnical engineer through nearly two decades as a professor of civil engineering at the University of Ottawa, Dr. Fellenius has made outstanding contributions in the international arena to the development and advancement of innovative approaches and practical methods for incorporating full-scale testing in foundation design, especially for deep foundations. This collection contains 51 papers on the use of full-scale testing to enhance the design of foundations. Eighteen papers are reprints of landmark articles authored or co-authored by Dr. Fellenius. Thirty-three additional peer-reviewed papers written especially for this collection present test methods for various types of foundations and describe useful applications in a diversity of situations. These papers offer findings from interesting projects and document valuable lessons learned by some of the leading experts in the field of foundation engineering from around the world. Full-Scale Testing and Foundation Design contains technical and practical information that will be valuable to geotechnical engineers, foundation specialists, researchers, and construction engineers.

Although finite element courses have become more popular in the undergraduate and graduate engineering, science, and applied mathematics curricula, there are very few introductory textbooks geared toward students accustomed to using computers for everyday assignments and research. 'An Introduction to Linear and Nonlinear Finite Element Analysis' fills this gap, offering a concise, integrated presentation of methods, applications, computational software tools, and hands-on programming projects. Suitable for junior/senior undergraduate and first-year graduate courses, the book is aimed at students from a variety of disciplines: engineering, physics, geophysics, and applied mathematics.
Unlike existing texts designed with specific applications to a particular field of mechanical, civil, or chemical engineering, the emphasis here is on interdisciplinary applications. One- and two-dimensional linear and nonlinear initial/boundary value problems are solved using finite element, Newton's, and conjugate gradient methods. Mathematical theory is kept to a minimum, making the text accessible to students with varied backgrounds.
