Simplified Computations for Effective Moment of Inertia Ie and Minimum Thickness to Avoid Deflection Computations
Author: Jacob S. Grossman | Size: 1.51 MB | Format:PDF | Year: 1981 | Publisher: ACI JOURNAL, Proceedings V. 78, No. 6, Nov.-Dec. 1981, pp. 423-439.
An approximate simplified procedure is described for estimating the effective moment of inertia I, for beams, T-beams, or one-way slabs constructed of normal weight aggregate concrete or lightweight concrete, and reinforced with 40-80 ksi reinforcing bars. The results are compatible with Ie values obtained from Eq. (9-7) of ACI 318-77. The simplified equations do not require computations for moment of inertia of the cracked section Icr, nor the reinforcing requirements initially. Also described is a simplified procedure for establishing minimum member depth so that deflection computations to ascertain serviceability may be avoided when designing the majority of one-way members

Shell structures are found abundantly in engineering designs and are routinely analysed with finite element methods. The objective of this book is to present, in a unified manner, modern finite element procedures for general shell analysis. The first chapters introduce the basic concepts for the analysis of shells, explain the mathematical preliminaries, and discuss the mathematical models of plates and shells including their asymptotic properties. The following chapters deal with finite element discretization methods for plates and shells. At the end of the book, applications of these methods in modern engineering practice are described and an overview of nonlinear shell analysis is given.
Review
From the reviews:
"The major part of the book focuses on the linear analysis of shell structures, for which a discussion of the available mathematical models and discretization procedures is given. … The aim of the present volume is to provide more powerful finite element methods by a deeper physical understanding of shell structural behavior and application of stronger mathematical theories. … This well-written text is not just a survey of finite element methods for shell analyses, but presents the authors’ experiences with shell analysis methods." (K.Marti, ZAMM - Zeitschrift für Angewandte Mathematik und Mechanik, Vol. 85 (2), 2005)
"If we are aware of the rising application of finite shell elements in industrial applications and of the growing size of the problems, an increase of mathematical knowledge for element use and development seems to be required. Just this is the aim of the present book … . This book is recommended to all ‘applied mechanicians’, who intend to study the mathematical backgrounds of finite shell analyses. For all developers of advanced and more powerful finite shell element techniques, its reading is a ‘must’." (Technische Mechanik, Vol. 24 (1), 2004)
"The main objective is to combine the fundamentals of shell theories, mathematical analyses and finite element methods in order to develop shell finite element approximations which are reliable and effective. … The expertises of both authors combined with a very clear and attractive presentation lead to a wonderful masterpiece which is, with no doubt and for a long time, the great reference book for the development of accurate and reliable numerical methods in the thin shell world." (Michel Bernadou, Zentralblatt MATH, Vol. 1103 (5), 2007)

Hardback
ISBN: 9780521806206
Publication date: April 2009
416 pages
This is the first complete account of the physics of the creep and fracture of ice, and their interconnectivity. It investigates the deformation of low-pressure ice, which is fundamental to glaciers, polar ice sheets and the uppermost region of icy moons of the outer Solar System. The book discusses ice structure and its defects, and describes the relationship between structure and mechanical properties. It reviews observations and measurements, and then interprets them in terms of physical mechanisms. The book provides a road-map to future studies of ice mechanics, such as the behaviour of glaciers and ice sheets in relation to climate change and the dating of deep ice cores. It also highlights how this knowledge is transferable into an understanding of other crystalline materials. Written by experts in the field, it is ideal for graduate students, engineers and scientists in Earth and planetary science, and materials science.
Features
• Critically reviews creep and fracture of ice from physical mechanism perspective, enabling reader to understand deformation of ice within conceptual framework of materials science
• Includes applications to creep of glaciers and ice sheets and to fracture of floating ice covers and ice forces on structures, linking science to engineering, research to field work
• Applies knowledge of ice to metals, rock and minerals, developing appreciation of physical interconnectedness of creep and fracture across a range of crystalline materials
