Download or read book Torsion of Thin Walled Structures written by Krishnaiyengar Rajagopalan and published by Springer Nature. This book was released on 2022-02-03 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive textbook focuses on the torsion in thin walled structures, highlights the nuances of the problems faced and succinctly discusses warping, bimoment, etc. Since in several thin walled structures, torsion is the only or dominant loading, this book addresses such unique structures as well. It provides a concise explanation of the warping properties and how they are evaluated. Thin walled structures with torsion as the preponderant loading are then treated using classical and finite element methods. No prior knowledge of the finite element method is required as the method is introduced from the basics. The same problem is worked out by both approaches so that the concepts are clearly understood by the readers. The book includes pedagogical features such as end-of-chapter questions and worked out examples to augment learning and self-testing. The book will be useful for graduate courses as well as for professional development coursework for structural engineers in the aerospace, mechanical, and civil engineering domains.
Download or read book Staircases Structural Analysis and Design written by M.Y.H. Bangash and published by Routledge. This book was released on 2019-07-16 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years both free-standing and geometric staircases have become quite popular. Many variations exist, such as spiral, helical, and elliptical staircases, and combinations of these. A number of researchers have come forward with different concepts in the fields of analytical and numerical design and of experimental methods and assessments. The aim of this book is to cover all these methods and to present them with greater simplicity to practising engineers. Staircases is divided into five chapters: Specifications and basic data on staircases; Structural analysis of staircases – Classical methods; Structural analysis of staircases – Modern methods; Staircases and their analysis – A comparative study; Design analysis and structural detailing. Charts and graphs are included and numerous design examples are given of freestanding and other geometric staircases and of their elements and components. These examples are related to the case studies which were based on staircases that have already been constructed. All examples are checked using various Eurocodes. The book includes bibliographical references and is supported by two appendices, which will be of particular interest to those practising engineers who wish to make a comparative study of the different practices and code requirements used by various countries; detailed drawings are included from the USA, Britain, Europe and Asia. Staircases will serve as a useful text for teachers preparing design syllabi for undergraduate and post graduate courses. Each major section contains a full explanation which allows the book to be used by students and practising engineers, particularly those facing the formidable task of having to design/ detail complicated staircases with unusual boundary conditions. Contractors will also find this book useful in the preparation of construction drawings and manufacturers will be interested in the guidance given.

Available in PDF, EPUB and Kindle. Book excerpt: Finally, the dynamic analysis was conducted to investigate the seismic response of asymmetric structural systems by taking into account the torsional resistance of wall element and its interaction with flexure. A numerical, step-by-step integration procedure (average acceleration method) was used to solve the equation of motion. The element forces (torsion and flexure) obtained at the previous time step were used to determine the flexural and torsional hysteretic relations of the current time step through interaction curves. Three real earthquake waves were selected and scaled to various PGA levels ranged between 0.1g and 1g with an interval of 0.1g. Three series of models with varying levels of plan-asymmetry, respectively characterized by large (erx/A=0.47), medium (erx/A=0.21) and small (erx/A=0.06) eccentricities, were adopted in the analysis. The analytical results showed that the torsional resistance of the wall element could be substantially mobilized by large rotational displacement under seismic excitation. Simultaneously, the flexural resistance of the wall could also be utilized. As a result, the torsional resistance of the wall and its interaction with flexure would have an influence on the seismic response of asymmetric buildings. It was found that the exclusion of the torsional resistance of the wall does not always lead to a conservative estimation of the system response. First, the flexure-torsion interaction effect did not play a significant role in the peak lateral displacement at CM, the peak slab rotation and the peak displacement of flexible wall. These parameters were underestimated to varying degrees under low-to-medium PGA levels, which ranged from 0.2g to 0.6g depending on the characteristics of the ground motion, if either the wall torsion or the interaction effect was ignored. On the other hand, the displacement of stiff wall was affected by the flexure-torsion interaction in a significant way. The displacement tended to be underestimated under most of the selected levels of ground motion if the interaction effect was neglected. In addition, as expected, the effect of wall torsion on the system response was more significant for the models with greater plan-asymmetry. However, even for the models with less plan-asymmetry, the system response could be underestimated by as much as 20% if the wall torsion was ignored.
Download or read book Seismic Behaviour and Design of Irregular and Complex Civil Structures IV written by Rita Bento and published by Springer Nature. This book was released on 2022-01-18 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains papers of the 9th European Workshop on the Seismic Behaviour of Irregular and Complex Structures (9EWICS) held in Lisbon, Portugal, in 2020. This workshop, organized at Instituto Superior Técnico, University of Lisbon, continued the successful three-annual series of workshops started back in 1996. Its organization had the sponsorship of Working Group 8 (Seismic Behaviour of Irregular and Complex Structures) of the European Association of Earthquake Engineering.This international event provided a platform for discussion and exchange of ideas and unveiled new insights on the possibilities and challenges of irregular and complex structures under seismic actions. The topics addressed include criteria for regularity, seismic design of irregular structures, seismic assessment of irregular and complex structures, retrofit of irregular and complex structures, and soil-structure interaction for irregular and complex structures. Beyond an excellent number of interesting papers on these topics, this volume includes the papers of the two invited lectures – one devoted to irregularities in RC buildings, including perspectives in current seismic design codes, difficulties in their application and further research needs, and another one dedicated to the challenging and very up to date topic in the area of seismic response of masonry building aggregates in historical centers. This volume includes 26 contributions from authors of 11 countries, giving a complete and international view of the problem.The holds particular interest for all the community involved in the challenging task of seismic design, assessment and/or retrofit of irregular and complex structures.
Download or read book Structural Analysis of Regular Multi Storey Buildings written by Karoly A. Zalka and published by CRC Press. This book was released on 2012-07-05 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sound and more modern Eurocode-based approach to design is the global approach, where the structures are considered as whole units, rather than to use traditional element-based design procedures. Although large frameworks and even whole buildings are now routinely analysed using computer packages, structural engineers do not always understand complex three-dimensional behaviour and thus manipulate the stiffness and the location of the bracing units to achieve an optimum structural arrangement. This guide deals with two categories of multi-storey structures. It can be used for the plane stress, stability and frequency analysis of individual bracing units such as frameworks, coupled shear walls and cores. In addition, and perhaps more importantly, it can be used for the three dimensional stress, stability and frequency analysis of whole buildings consisting of such bracing units. The closed-form solutions in the book may also prove to be useful at the preliminary design stage when quick checks are needed with different structural arrangements. Their usefulness cannot be overemphasized for checking the results of a finite element (computer-based) analysis when the input procedure involves tens of thousands of items of data and where mishandling one item of data may have catastrophic consequences. In addition to the critical load, the fundamental frequency, the maximum stresses and the top deflection of frameworks, coupled shear walls, cores and their spatial assemblies, a very important new piece of information is the "safety factor" of the structure (either a single unit or a whole building), which also acts as the performance indicator of the structure. MathCAD worksheets can be downloaded from the book’s accompanying website.
