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.

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.

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.

Dieses Buch führt in alle Aspekte der sicheren Berechnung, Bemessung und Konstruktion von wirtschaftlichen modernen Verbindungen im Stahlbau ein. Die Hintergrunderläuterungen sind nicht an eine spezifische Norm gekoppelt, sondern es werden unterschiedliche Normen und Methoden verglichen, die in der Praxis zur Anwendung kommen, wie z. B. Eurocode, AISC, DIN, BS. Anhand einer Reihe von Beispielen werden Problemlösungen detailliert beschrieben und illustriert. Damit erhält der Leser alle notwendigen Werkzeuge an die Hand, um auch komplexe Probleme bei der Konstruktion von Verbindungen zu lösen. Das Buch ist für Berufseinsteiger, für erfahrene Praktiker sowie auch für Stahlbaufachleute eine Arbeitshilfe, denn es werden einfache und komplexe Beanspruchungen an Verbindungen abgebildet. Weniger ausführlich werden Erdbebenauslegung, Schweißnähte, die Wechselwirkung mit anderen Materialien (Beton, Holz) und kalt geformte Verbindungen behandelt.

These two volumes of proceedings contain nine invited keynote papers and 130 contributed papers presented at the Third International Conference on Advances in Steel Structures (ICASS '02) held on 9-11 December 2002 in Hong Kong, China. The conference is a sequel to the First and the Second International Conferences on Advances in Steel Structures held in Hong Kong in December 1996 and 1999. The conference provides a forum for discussion and dissemination by researchers and designers of recent advances in the analysis, behaviour, design and construction of steel structures. Papers were contributed from over 18 countries around the world. They report current state-of-the art and point to future directions of structural steel research, covering a wide spectrum of topics including: beams and columns; connections; scaffolds and slender structures; cold-formed steel; composite construction; plates; shells; bridges; dynamics; impact mechanics; effects of welding; fatigue and fracture; fire performance; and analysis and design.

Diagrids are load-bearing structures made of steel diagonal grids. They were first used in the great buildings of the turn of the millennium, such as the Swiss Re Tower in London (“The Gherkin”) and the Hearst Magazine Tower in New York City. Dagrids owe their ensuing popularity not only to their stunning aesthetic value, but also to their very tangible benefits: lateral loading capacity, a massive saving of material, a significant gain in open, usable floor area, and increased flexibility. At its opening in 2014, the Leadenhall Building in London will be the first skyscraper without a bearing inner core—thanks to a diagrid structure. This book explains comprehensively for the first time all of the aspects involved in this new bearing structure. The author, experienced in teaching, research, and practice (recent publication: Understanding Steel Design. An Architectural Design Manual, 2011), has tracked the development of this technology from its beginnings and employs photographic documentation of the construction phases of many diagrid structures.
