Complex Steel Structures

Complexity in architecture, construction and material manipulation is constantly increasing due to our present ability to design, calculate and fabricate an extending range of geometric shapes and systems. This volume addresses the design of complexity in the planning, fabrication and construction of steel structures based on non-orthogonal geometries: curved and chaotic geometries, poly-diagrid systems, lattice-grid structures and others. Topical photographs by the author on a wide range of international projects present innovative methods and techniques, providing an excellent understanding of the possibilities and requirements of complex steel structures.

The third edition of this popular book now contains references to both Eurocodes and British Standards, as well as new and revised examples, and sections on sustainability, composite columns and local buckling. Initial chapters cover the essentials of structural engineering and structural steel design, whilst the remainder of the book is dedicated to a detailed examination of the analysis and design of selected types of structures, presenting complex designs in an understandable and user-friendly way. These structures include a range of single and multi-storey buildings, floor systems and wide-span buildings. Emphasis is placed on practical design with a view to helping undergraduate students and newly qualified engineers bridge the gap between academic study and work in the design office. Experienced engineers who need a refresher course on up-to-date methods of design and analysis will also find the book useful.

The plastic analysis method has been used extensively by engineers for designing steel structures. Simpler structures can be analyzed using the basic virtual work formulation, but more complex frames are evaluated with specialist computer software. This new book sets out a method for carrying out plastic analysis of complex structures without the need for specialist tools. The book provides an introduction to the use of linear programming techniques for plastic analysis. This powerful and advanced method for plastic analysis is important in an automated computational environment, in particular for non-linear structural analysis. A detailed comparison between the design codes for the United States and Australia and the emerging European Eurocodes enables practising engineers to understand the issues involved in plastic design procedures and the limitations imposed by this design method. * Covers latest research in plastic analysis and analytical tools * Introduces new successive approximation method for calculating collapse loads * Programming guide for using spreadsheet tools for plastic analysis

This book provides the means for a better control and purposeful consideration of the design of Architecturally Exposed Structural Steel (AESS). It deploys a detailed categorization of AESS and its uses according to design context, building typology and visual exposure. In a rare combination, this approach makes high quality benchmarks compatible with economies in terms of material use, fabrication methods, workforce and cost. Building with exposed steel has become more and more popular worldwide, also as advances in fire safety technology have permitted its use for building tasks under stringent fire regulations. On her background of long standing as a teacher in architectural steel design affiliated with many institutions, the author ranks among the world‘s best scholars on this topic. Among the fields covered by the extensive approach of this book are the characteristics of the various categories of AESS, the interrelatedness of design, fabrication and erection of the steel structures, issues of coating and protection (including corrosion and fire protection), special materials like weathering steel and stainless steel, the member choices and a connection design checklist. The description draws on many international examples from advanced contemporary architecture, all visited and photographed by the author, among which figure buildings like the Amgen Helix Bridge in Seattle, the Shard Observation Level in London, the New York Times Building and the Arganquela Footbridge.

First book to discuss the analysis of structural steel connections by Finite Element Analysis—which provides fast, efficient, and flexible checking of these vital structural components The analysis of steel structures is complex—much more so than the analysis of similar concrete structures. There are no universally accepted rules for the analysis of connections in steel structures or the analysis of the stresses transferred from one connection to another. This book presents a general approach to steel connection analysis and check, which is the result of independent research that began more than fifteen years ago. It discusses the problems of connection analysis and describes a generally applicable methodology, based on Finite Element Analysis, for analyzing the connections in steel structures. That methodology has been implemented in software successfully, providing a fast, automatic, and flexible route to the design and analysis of the connections in steel structures. Steel Connection Analysis explains several general methods which have been researched and programmed during many years, and that can be used to tackle the problem of connection analysis in a very general way, with a limited and automated computational effort. It also covers several problems related to steel connection analysis automation. Uses Finite Element Analysis to discuss the analysis of structural steel connections Analysis is applicable to all connections in steel structures The methodology is the basis of the commercially successful CSE connection analysis software Analysis is fast and flexible Structural engineers, fabricators, software developing firms, university researchers, and advanced students of civil and structural engineering will all benefit from Steel Connection Analysis.

This textbook covers the design and analysis of steel structures for buildings according to EN 1990 (Eurocode 0), EN 1991 (Eurocode 1) and EN 1993 (Eurocode 3). Chapter 1 describes the theory and background of EN 1990 in terms of structural safety, reliability and the design values of resistances and actions. Chapter 2 deals with actions and deformations described in EN 1991. The permanent loads and vari¬able actions and in particular the imposed loads and the snow loads and wind actions are discussed. This chapter also contains three worked examples to determine the actions on a floor in a residential house, the actions on a free-standing platform canopy at a station and the wind actions on the façades of an office building. Chapter 3 is about modelling, discussing the schematisation of the structural system, the joints and the material properties as well as the cross-section properties. Chapter 4 deals with the classification of frames and the various analysis methods for unbraced and braced frames. Chapter 5 then goes deeper into these analysis methods to determine the force distribution and defor¬mations. Chapter 6 deals with the assessment by code-checking of (parts of) the steel structure with EN 1993-1-1 and EN 1993-1-8. At a basic level, the assessment of the resistance of cross-sections, the stability of members under axial forces and the resistance of bolted and welded connections are explained. Chapter 7 discusses in an extensive way the assessment by code-checking of the resistance of cross-sections, both for single and combined internal forces. The principles of the assessment of the resistance of cross-sections according to elastic and plastic theory are also discussed.
