CE-411, Steel Design Fifth Edition

Abstract

Steel Design, Fifth Edition covers the fundamentals of structural steel design for buildings. This book is intended for junior-and senior-level engineering students, although some of the later chapters can be used in a combination undergraduate/graduate course. Practicing civil engineers who need a review of current practice and the current AISC Specification and Manual will find the book useful as a reference. Students should have a background in mechanics of materials and analysis of statically determinate structures. Knowledge of statically indeterminate structural analysis is not a prerequisite for the use of this book. Structural design is a complex endeavor, involving the synthesis of many processes. This book does not cover the integrated design of buildings, but presents some of the “building blocks” for structural steel design. We focus on the analysis and design of individual members and connections, rather than complete structures. Prior to the 2005 Specification and Manual of the American Institute of Steel Construction, load and resistance factor design (LRFD) was covered by the 1999 AISC Specification and LRFD Manual of Steel Construction, Third Edition. Allowable stress design (ASD) was covered by the 1978 AISC Specification and Manual of Steel Construction, Ninth Edition. In 2005, the two approaches were unified in a single specification and a single manual, the thirteenth edition of the Steel Construction Manual. In addition, changes were made to many provisions of the specification, both in form and substance. The unified approach continues with the 2010 Specification and the 14th edition of the Steel Construction Manual. Both documents have been revised to reflect current research and practice, but the format remains the same. Both LRFD and ASD are covered in this textbook, but the emphasis is on LRFD. In most examples, both LRFD and ASD solutions are given. In those examples, the LRFD solution is given first. In some cases, the ASD solution is abbreviated but complete and independent of the LRFD solution. This usually involves some duplication but is necessary if a reader is interested in only the ASD solution. In some ASD solutions where there would be a lengthy duplication, the reader is referred to the LRFD solution for that portion. In some of the examples, particularly in the later chapters, only an LRFD solution is given. This is in keeping with the approach
