Design Of Welded Tubular Connections

Although tubular structures are reasonably well understood by designers of offshore platforms, onshore applications often suffer from "learning curve" problems, particularly in the connections, tending to inhibit the wider use of tubes. This book was written primarily to help this situation. Representing 25 years of work by one of the pioneers in the field of tubular structures, the book covers research, synthesis of design criteria, and successful application to the practical design, construction, inspection, and lifetime monitoring of major structures. Written by the principal author of the AWS D1.1 Code Provisions for Tubular Structures this book is intended to be used in conjunction with the AWS Structural Welding Code - Steel, AWS D1.1-88 published by the American Welding Society, Miami, FL, USA. Users of this Code, writers of other codes, students and researchers alike will find it an indispensable source of background material in their work with tubular structures.

Part of a series that details the method of design and provides design capacity tables and detailing parameters for a range of tubular connections commonly used in Australia. This design guide on fully welded simple planar connections covers connections of single brace members into chord members where there is no or limited interaction with adjacent brace members.

This topical book contains the latest scientific and engineering developments in the field of tubular steel structures, as presented at the "11th International Symposium and IIW International Conference on Tubular Structures". The International Symposium on Tubular Structures (ISTS) has a long-standing reputation for being the principal showcase for manufactured tubing and the prime international forum for discussion of research, developments and applications in this field. Various key and emerging subjects in the field of hollow structural sections are covered, such as: novel applications and case studies, static and fatigue behaviour of connections/joints, concrete-filled and composite tubular members, earthquake resistance, specification and code developments, material properties and structural reliability, impact resistance and brittle fracture, fire resistance, casting and fabrication innovations. Research and development issues presented in this book are applicable to buildings, bridges, offshore structures, entertainment rides, cranes, towers and various mechanical and agricultural equipment. This book is thus a pertinent reference source for architects, civil and mechanical engineers, designers, steel fabricators and contractors, manufacturers of hollow sections or related construction products, trade associations involved with tubing, owners or developers of tubular structures, steel specification committees, academics and research students. The conference presentations herein include two keynote lectures (the International Institute of Welding Houdremont Lecture and the ISTS Kurobane Lecture), plus finalists in the CIDECT Student Papers Competition. The 11th International Symposium and IIW International Conference on Tubular Structures – ISTS11 – took place in Québec City, Canada from August 31 to September 2, 2006.

Part of a series that details the method of design and provides design capacity tables and detailing parameters for a range of tubular connections commonly used in Australia. This design guide on fully welded overlap planar connections covers connections of two or more brace members into a chord member, where the adjacent brace members along the connected face of the chord member are overlapped.

Introduction -- Load & stress analysis -- Column-related design -- Girder-related design -- Welded-connection design -- Miscellaneous structure design -- Joint design and production -- Reference design formulas.

Part of a series that details the method of design and provides design capacity tables and detailing parameters for a range of tubular connections commonly used in Australia. This design guide on fully welded gap planar connections covers connections of two or more brace members framing into the same side of a chord member, where a gap exists between the adjacent brace members along the connected face of the chord member.

Welding of Tubular Structures focuses on the testing, techniques, and other processes connected with welding tubular structures in different conditions and environments. The selection features the works of individuals who have devoted time in the study of welding, particularly on tubular structures and other materials. The discussions focus on the design of connections of welded structures, including the process of welding and inspection. Attention is given to weldments on offshore structures, and primary concerns include the testing of the materials used and how these materials fall short if subjected to stress and fatigue. Different welding techniques used on offshore structures are also discussed. Welding techniques on other materials are also noted. These discussions are supported by studies that are backed up by numerical representations, which is aimed at validating the strength of welded materials. Consideration is given when these welded materials suffer from crack or fatigue. Analysis of the factors why these welded materials fail to meet standards is done. A comparative study is also conducted on aluminum, steel, and other products when these are subjected to stress in different conditions and environments. The book is a primary source of data to those in the welding sector, particularly those working in offshore structures.

Cold formed structural members are being used more widely in routine structural design as the world steel industry moves from the production of hot-rolled section and plate to coil and strip, often with galvanised and/or painted coatings. Steel in this form is more easily delivered from the steel mill to the manufacturing plant where it is usually cold-rolled into open and closed section members.This book not only summarises the research performed to date on cold form tubluar members and connections but also compares design rules in various standards and provides practical design examples.
