State-of-the-art coverage of modern computational methods for theanalysis and design of beams Analysis and Design of Elastic Beams presents computer models andapplications related to thin-walled beams such as those used inmechanical and aerospace designs, where thin, lightweightstructures with high strength are needed. This book will enablereaders to compute the cross-sectional properties of individualbeams with arbitrary cross-sectional shapes, to apply ageneral-purpose computer analysis of a complete structure todetermine the forces and moments in the individual members, and touse a unified approach for calculating the normal and shearstresses, as well as deflections, for those members' crosssections. In addition, this book augments a solid foundation in the basicstructural design theory of beams by: * Providing coverage of thin-wall structure analysis andoptimization techniques * Applying computer numerical methods to classical designmethods * Developing computational solutions for cross-sectional propertiesand stresses using finite element analyses Including access to an associated Web site with software for theanalysis and design of any cross-sectional shape, Analysis andDesign of Elastic Beams: Computational Methods is an essentialreference for mechanical, aerospace, and civil engineers anddesigners working in the automotive, ship, and aerospace industriesin product and process design, machine design, structural design,and design optimization, as well as students and researchers inthese areas.

There has been a growing interest in the foundation of the theory of th- walled composite beams and of their incorporation in aeronautical/aerospace, automotive, helicopter and turbomachinery rotor blades, mechanical,civil and naval constructions inthe last two decades or so. The proliferation of the specialized literature, mainly in the form of journal/ proceedings papers, and the activity in terms of workshops devoted to this topic attest this interest. A decisive factor that has fueled thisgrowing activity was generatedby highdiversity and severity ofdemandsand operating conditions imposed on structural elements involvedintheadvanced technology. In order to beable to survive andful?ll theirmission inthe extreme environmental conditions inwhich they operate, new materialsand new structural paradigms are required. The new exotic structures have to provide higher performances, unatta- able bytheclassical structures builtof traditional materials. Theadvent of advanced composite materials, of smart materialsandfunctionally graded - terials (FGMs), have constituted the strongest stimuli for suchdevelopments. Moreover, their incorporation is likely to expand the use and capabilities of thin-walledbeam structures. Thenew and stringent requirements imposed on aeronautical/aerospace, turbomachinery and shaft structural systems will be best met by such new types of material structures.

The book describes analytical methods (based primarily on classical modal synthesis), the Finite Element Method (FEM), Boundary Element Method (BEM), Statistical Energy Analysis (SEA), Energy Finite Element Analysis (EFEA), Hybrid Methods (FEM-SEA and Transfer Path Analysis), and Wave-Based Methods. The book also includes procedures for designing noise and vibration control treatments, optimizing structures for reduced vibration and noise, and estimating the uncertainties in analysis results. Written by several well-known authors, each chapter includes theoretical formulations, along with practical applications to actual structural-acoustic systems. Readers will learn how to use vibroacoustic analysis methods in product design and development; how to perform transient, frequency (deterministic and random), and statistical vibroacoustic analyses; and how to choose appropriate structural and acoustic computational methods for their applications. The book can be used as a general reference for practicing engineers, or as a text for a technical short course or graduate course.

The book covers the application of numerical methods to reinforced concrete structures. To analyze reinforced concrete structures linear elastic theories are inadequate because of cracking, bond and the nonlinear and time dependent behavior of both concrete and reinforcement. These effects have to be considered for a realistic assessment of the behavior of reinforced concrete structures with respect to ultimate limit states and serviceability limit states. The book gives a compact review of finite element and other numerical methods. The key to these methods is through a proper description of material behavior. Thus, the book summarizes the essential material properties of concrete and reinforcement and their interaction through bond. These basics are applied to different structural types such as bars, beams, strut and tie models, plates, slabs and shells. This includes prestressing of structures, cracking, nonlinear stressstrain relations, creeping, shrinkage and temperature changes. Appropriate methods are developed for each structural type. Large displacement and dynamic problems are treated as well as short-term quasi-static problems and long-term transient problems like creep and shrinkage. Most problems are illustrated by examples which are solved by the program package ConFem, based on the freely available Python programming language. The ConFem source code together with the problem data is available under open source rules at concrete-fem.com. The author aims to demonstrate the potential and the limitations of numerical methods for simulation of reinforced concrete structures, addressing students, teachers, researchers and designing and checking engineers.

Using aspects of structural behaviour, good design practice and effective computational techniques to illustrate the importance of the fundamental theoretical concepts presented, this book provides a comprehensive introduction to the analysis and design of structures. The over-riding importance of equilibrium is emphasized and, together with related topics, is the subject of the first five chapters. After deflections have been introduced in chapter six, elastic theory, buckling, plastic theory and energy methods are all introduced and their range of applicability discussed. Numerous case studies are included to help readers gain an appreciation of how theory relates in practice to real life structures. With a broad range of worked examples, questions and references to further reading, Structures is the ideal course text for entry-level students on degree, HNC and HND courses.

This book is designed to give the structural engineer training in microcomputer technology, starting with theory and computer methods in Part 1 and culminating in extensive listings of programs in both Fortran 77 and Basic in Part 2. Because it provides programs and the information to understand and modify them for specific purposes, it can be used as a text for graduate engineering students or by the professional engineer interested in learning how computers can be applied to practical problems. Data files and worked solutions are included. Some forty programs are explained ranging from cross-sectional and connection analysis, through equation solution methods to linear elastic analysis of plane and space frames, as well as describing the non-linear and large deformation treatment of a variety of frame, cable and arch structures. This new edition extensively revises the chapter on beam analysis, with more powerful theory and programs suitable to the microcomputers of today.
