Fatigue Design Procedure for Welded Hollow Section Joints


Book Description

This International Institute of Welding (IIW) report was presented at the 52nd Annual Assembly in Lisbon in June 1999. It contains recommendations representing a consensus on international best practice, focusing on a 'hot spot stress' approach.A wide range of joint types is covered, the new fatigue design curve for both RHS and CHS is dealt with and detailed values for stress concentration factors are provided.The purpose of this current IIW document is to serve both as an International Standards Organisation (ISO) draft specification and as a model standard for national and regional specifications worldwide.The Recommendations (Part one) and Commentary (Part two) were edited by Dr X-L Zhao of Monash University, Australia and Professor J A Packer of the University of Toronto, Canada.

Tubular Structures XI


Book Description

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.




Recommendations for Fatigue Design of Welded Joints and Components


Book Description

This book provides a basis for the design and analysis of welded components that are subjected to fluctuating forces, to avoid failure by fatigue. It is also a valuable resource for those on boards or commissions who are establishing fatigue design codes. For maximum benefit, readers should already have a working knowledge of the basics of fatigue and fracture mechanics. The purpose of designing a structure taking into consideration the limit state for fatigue damage is to ensure that the performance is satisfactory during the design life and that the survival probability is acceptable. The latter is achieved by the use of appropriate partial safety factors. This document has been prepared as the result of an initiative by Commissions XIII and XV of the International Institute of Welding (IIW).




Cold-formed Tubular Members and Connections


Book Description

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.




Tubular Structures XVI


Book Description

Tubular Structures XVI contains the latest scientific and engineering developments in the field of tubular steel structures, as presented at the 16th International Symposium on Tubular Structures (ISTS16, Melbourne, Australia, 4-6 December 2017). 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 presentation and 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: special applications and case studies, static and fatigue behaviour of connections/joints, concrete-filled and composite tubular members and offshore structures, earthquake and dynamic resistance, specification and standard developments, material properties and section forming, stainless and high-strength steel structures, fire, impact and blast response. Research and development issues presented in this topical book are applicable to buildings, bridges, offshore structures, cranes, trusses and towers. Tubular Structures XVI 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 all around the world.




Contribution on the behavior of welded joints to metallic structural elements with tubular section


Book Description

Doctoral Thesis / Dissertation from the year 2022 in the subject Engineering - Civil Engineering, grade: Summa cum laude, , language: English, abstract: Steel structures, which are made of hollow section profiles are mainly used for construction structures. There are many fields of applications for structures made of hollow section profiles. Hollow section profiles are lightweight and have got a high resistance to compression, which is an advantage for column structures. The most common profile types have squared or circular hollow cross sections. Connecting two or more pipes by welding, the joints have got different shapes. These joints are part of trusses or columns with a tree-shaped optic. The standards have got restrictions regarding the geometry, material or load cases. By choosing a node, which is excluded in the standards, designing engineers have to create their own models. This thesis is about the designing of a Y-shaped steel joint, full overlapped on top connection, which is not defined in current standards up to the time the thesis is created. In this thesis only uniplanar joints are investigated. A special focus is on the welding line, which has got a three-dimensional shape. The aim is to figure out the influence on the inclination angle between the two members on the resistance of the joint. Beside this, the profile shape and profile thickness vary to see the differences in their resistance. Square and circular hollow section profiles are in focus. To analyse the behaviour of the different steel joints, a numerical and experimental investigation is executed. Design charts are created as a medium for designing engineers to calculate the ultimate resistance in the elastic and plastic state, depending on the steel profile, thickness and inclination angle. The structure of the thesis is split into four main parts. Firstly, there is an explanation of the general topic with its difficultness. Secondly, there is the state-of-the-art presentation of literature and standards in this range. Thirdly, there is a numerical analysis of the joints. The basement of the numerical studies is detailed in pre-studies, which explain and compare different mesh types or geometrical variations. Fourthly, there is an experimental verification of the numerical tests. It is figured out, if the inclination angle increase, the resistance of the steel joint will decrease significantly. This effect is non-linear. Beside this, it is found, that the full overlapped joint with the squared profile has got a higher resistance than a comparable joint with a similar circular hollow section.
