Design Of Steel Structures Vol 2

Eight edition of this book is based on Bridge Rules (Adopted in 1941, Revised in 1964 and Reprinted in 1989), and IS: 800-2007. Authors have distributed present text in the edition in thirty two chapters [that is, in Four parts (1) Steel Bridges and Influence Lines Diagrams for axial forces for the members of different types of truss-girders, (2) Special Steel Structures (3) Analysis of Structures specially, the method of tension co-efficients for determinate and indeterminate structures, (4) Aluminium structures. In order to emphasize that similar to various other subjects, this subject is also very vast. Therefore, space steel structures and stressed-skin steel structures have been described special features of this new-edition of this book may be mentioned as under (1) Historical development of different types of steel bridges details of some spans of longest spans of various types of steel bridges, (2) Design of Guyed Steel Chimneys (3) Instantaneous Centre of Rotation (ICR) and Plastic Analysis of Pitched slope (i.e., gable structure) and influences of axial forces and shear forces on the plastic moment of resistance of the member cross-sections.

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.

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.

This book is intended for classroom teaching in architectural and civil engineering at the graduate and undergraduate levels. Although it has been developed from lecture notes given in structural steel design, it can be useful to practicing engineers. Many of the examples presented in this book are drawn from the field of design of structures. Design of Steel Structures can be used for one or two semesters of three hours each on the undergraduate level. For a two-semester curriculum, Chapters 1 through 8 can be used during the first semester. Heavy emphasis should be placed on Chapters 1 through 5, giving the student a brief exposure to the consideration of wind and earthquakes in the design of buildings. With the new federal requirements vis a vis wind and earthquake hazards, it is beneficial to the student to have some under standing of the underlying concepts in this field. In addition to the class lectures, the instructor should require the student to submit a term project that includes the complete structural design of a multi-story building using standard design procedures as specified by AISC Specifications. Thus, the use of the AISC Steel Construction Manual is a must in teaching this course. In the second semester, Chapters 9 through 13 should be covered. At the undergraduate level, Chapters 11 through 13 should be used on a limited basis, leaving the student more time to concentrate on composite construction and built-up girders.

First course for the learners of steel structural design at UG level, this book is based on limit state design as per the Indian Code of Practice – General construction in steel – IS 800-2007. It explains theoretical concepts which form the basis of codal provisions. Emphasis lies on principal axes based compression members, peripheral load distribution for base plates, limit state design of base plate bearing column with moment, unsymmetrically loaded beam design, tension field web design in plate girders, section and member design for bi-axially loaded beam columns which are unique to the book. Practical insight provided in chapters of applied design.

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.
