Limit State Design Of Steel Structures

Method of Limit State (Ultimate Limit State, (ULS) and serviceability limit state (SLS)) present an improved design philosophy and makes allow-ance for the short-compings of working stress method (conventional and long time used in practice). This method provides basic framework, within which the performance of the steel structures may be assessed against various limiting conditions and invo-lves some concept of probability. Object of limit design method is to get steel structure that will remain fit for use during its life with acceptable target reliability. The probability of a limit state being reached during its life time is kept very small. This method has been broadly adopted in many developed countries and based on the recommendations of IS: 800-2007 (Third Revised Edition). This method has been covered in nine parts (in twenty six chapters and four appendices) as listed in contents. After introducing `Limit State Method of Design of Concrete Structures (LSD: CC) in IS: 456-1978, it was natural for Bureau of Indian Standard to introduce `Limit State Design of Steel Structures (LSD: SS). SI units for text for complete book, uncertainties involved in the working stress method and the concept of partial safety factors for the loads and strength of mate-rials (for yield and ultimate stresses reached) are the special feature of the book. Concepts of shear centre for thin-walled beam cross-sections and unsymmetrical bending of beams are important for various requirements and have been included in appendices. The text of book has been covered in about 1000 pages and 550 diagrams. The texts of various topics has been explained in many illustrative worked-out examples.

The second edition has incorporated all the revisions necessitated after the issue of Amendment No. 1 of January 2012 to IS 800:2007. The book is primarily designed for the students of civil/structural engineering at all levels of studies—undergraduate, postgraduate and diploma—as well as for the professionals in the field of structural steel design. It covers the fundamental concepts of steel design in the perspective of the limit state design concept as per IS 800:2007, with the focus on cost-effective design of industrial structures, foot bridges, portal frames, and pre-engineered buildings. The connection design details are discussed concurrently with the design of members. The book covers the subject matter, with the help of numerous practical illustrations accompanied by step-by-step design calculations and detail-ing, in 14 chapters—including a chapter on pre-engineered buildings. Solved examples as well as exercises are provided in each chapter to enable the development of a strong understanding of the underlying concepts and for testing the comprehension acquired by the students. The geometrical properties of rolled steel sections, often required as per the revised clauses of IS 800:2007 and not appearing in the existing steel tables, are given in the Appendix A for ready reference.

The Tenth Edition of this text introduces the changes in the 2014 edition of CSA-S16 standard and the 2013 edition of CSA-G40.20/G40.21. Since this textbook is intended to be used in conjunction with the 11th edition of the CISC Handbook of steel construction, the changes in the Handbook have also been adopted in the textbook. These changes, which reflect changes in the steel inductr4y, include adjustments to rolled steel shapes section properties to reflect a change in the flange to web transition radius, the deletion of some rolled shapes and welded wide flange (WWF) sections that are no longer produced in North American mills. With an expanding global market, some structural steel shapes, such as rolled wide flange sections, are becoming more prevalent in American steel grades (ASTM classification) whereas some shapes, such as plates, are still readily available in Canadian steel grades (CSA-G40.21 classification). Therefore American grade steels have been introduced in some of the design examples. Furthermore, since metric size bolts are only rarely used in the construction industry, the design tables for bolts and bolted connections presented in the CISC Handbook have abandoned metric size bolts. Therefore, imperial size bolts are mainly used in this new edition of the text. Divided into 11 chapters, the book covers tension members, flexural members, columns, beam-columns, stability, fatigue behaviour, connections, plate girders, composite construction, and types and grades of structural steel.

So far working stress method was used for the design of steel structures. Nowadays whole world is going for the limit state method which is more rational. Indian national code IS:800 for the design of steel structures was revised in the year 2007 incorporating limit state method. This book is aimed at training the students in using IS: 800 2007 for designing steel structures by limit state method. The author has explained the provisions of code in simple language and illustrated the design procedure with a large number of problems. It is hoped that all universities will soon adopt design of steel structures as per IS: 2007 and this book will serve as a good textbook.A sincere effort has been made to present design procedure using simple language, neat sketches and solved problems.

Steel plated structures are important in a variety of marine and land-based applications, including ships, offshore platforms, power and chemical plants, box girder bridges and box girder cranes. The basic strength members in steel plated structures include support members (such as stiffeners and plate girders), plates, stiffened panels/grillages and box girders. During their lifetime, the structures constructed using these members are subjected to various types of loading which is for the most part operational, but may in some cases be extreme or even accidental. Ultimate Limit State Design of Steel Plated Structures reviews and describes both fundamentals and practical design procedures in this field. The derivation of the basic mathematical expressions is presented together with a thorough discussion of the assumptions and the validity of the underlying expressions and solution methods. Particularly valuable coverage in the book includes: * Serviceability and the ultimate limit state design of steel structural systems and their components * The progressive collapse and the design of damage tolerant structures in the context of marine accidents * Age related structural degradation such as corrosion and fatigue cracks Furthermore, this book is also an easily accessed design tool which facilitates learning by applying the concepts of the limit states for practice using a set of computer programs which can be downloaded. In addition, expert guidance on mechanical model test results as well as nonlinear finite element solutions, sophisticated design methodologies useful for practitioners in industries or research institutions, selected methods for accurate and efficient analyses of nonlinear behavior of steel plated structures both up to and after the ultimate strength is reached, is provided. Designed as both a textbook and a handy reference, the book is well suited to teachers and university students who are approaching the limit state design technology of steel plated structures for the first time. The book also meets the needs of structural designers or researchers who are involved in civil, marine and mechanical engineering as well as offshore engineering and naval architecture.

This book on Design of Steel Structures uses Limit State Method and follows the latest BIS Codes, BIS: 800: 2007.A perfect mix of concise theory with relevant applications and inclusion of most recent design methodologies makes this an excellent offering to students and practicing engineers.

Twelfth edition, 2009 of this book is based on IS: 800-2007 and also newly revised IS: 883-1994 (code of practice for timber structures). New code of practice, IS: 800 is likely to be issued soon. It is likely to introduce ``Limit State Design of Steel Structures''. Authors have distributed the text in thirty four chapters in main text and one chapter `on Location of Shear Centre' in Appendix A. Concept of Shear Centre and bending axis is important and significant and essentially needed to understand simple theory of bending and so also unsymmetrical bending. Complete-text has been updated and new matter added (e.g., elastic buckling, inelastic, stability and instability of columns and compression members, torsional-buckling, torsional-flexural buckling, etc.). Behaviour of web-stiffeners and web-panels specially near the end panels, tension-field action has been first time included to familiarise the students with the concept. Durability of steel members have been emphasized phenomenon of corrosion has been distinctly explained.
