We appreciate our cooperation with highly respected, science driven, national and international organizations, which share our passion for hollow section steel structures, and which accompany us in our ambition to stimulate the development or enhancement of design codes and guidelines worldwide.

Since 1964, the International Institute of Welding (IIW) Commission XV has maintained a Sub-commission XV-E on “Welded Joints in Tubular Structures”. Now renamed simply “Tubular Structures”, the principal activities of this active sub-commission in recent times have been: (i) developing international standards; and (ii) organizing international symposia. Volunteer technical specialists serving on IIW XV-E study and synthesize technical information on tubular steel structures and periodically produce state-of-the-art design recommendations through IIW Commissions XV and XIII on the topic of static and fatigue strength of hollow section joints/connections. Through IIW’s role as a recognized ISO standardization body, two principal international standards have been developed and maintained by IIW XV-E:

1. ISO 14346, “Static design procedure for welded hollow-section joints – Recommendations”, International Standards Organization, Geneva, Switzerland, 2013;

2. ISO 14347, “Fatigue – Design procedure for welded hollow-section joints – Recommendations”, International Standards Organization, Geneva, Switzerland, 2008.

In addition to standardization activities, IIW XV-E has, since 1984, organized the “International Symposium on Tubular Structures” (ISTS) at various venues around the world on an approximate 2.5-year cycle. This conference has become the principal international forum for discussion of research, developments and applications in the field of onshore tubular structures. Fifteen of these symposia have been held to date, with the next scheduled for December 2017 in Melbourne, Australia”.

The current Chair of IIW Sub-commission XV-E is Professor Thomas Ummenhofer of Karlsruhe Institute of Technology, Germany

The Research Association for Steel Application (FOSTA) is a non-profit and legally autonomous research association within the steel sector. As an association, it represents the interests of the steel industry – as well as those of the users of the material steel and its various products – in the field of application research.

Research at the forefront of progress
FOSTA’s research focuses on a wide range of topics, whereby the research work is also oriented upon public debate. Topics such as resource efficiency and the reduction of CO2 emissions are also of relevance to FOSTA. The following areas of interest characterise FOSTA’s profile:

  • material behaviour
  • machining and processing
  • traffic technology
  • the building industry
  • environmental technology

Research management for steel
Applications and further developments for the material steel are continuously driven forward within the framework of research management. In addition to organising the necessary funding for research projects from public national and European sources as well as industry, FOSTA provides advice regarding the generation of ideas. It also provides support in the formation of appropriate consortia for new research projects, manages the progress of projects together with the research centres, runs the committee overseeing a project with the industrial partners, and contributes towards distributing the research results within a network of over 7,000 specialists.

The aim of ECCS is to promote the use of steelwork in the construction sector by the development of standards and promotional information. It also helps to influence decision makers through the management of working committees, publications, conferences, and by active representation on European and International Committees dealing with standardisation, research and development and education. ECCS is the only European organization which brings together the Steel Industry, the Fabrication and Contracting specialists, and the Academic world through an international network of construction representatives, steel producers, and technical centres.

The American Institute of Steel Construction (AISC), headquartered in Chicago, is a not-for-profit technical institute and trade association established in 1921 to serve the structural steel design community and construction industry in the United States.

AISC’s mission is to make structural steel the material of choice by being the leader in structural-steel-related technical and market-building activities, including: specification and code development, research, education, technical assistance, quality certification, standardization, and market development. AISC has a long tradition of service to the steel construction industry providing timely and reliable information.

As part of AISC’s mission, we emphasize: Increasing the structural steel industry’s share of the construction market; Unifying the industry with a common purpose; Supporting and improving the ability of the structural steel industry to be both innovative and competitive in a worldwide construction market. Since its establishment, AISC has conducted its numerous activities with a scrupulous sense of public responsibility. For this reason, and because of the high calibre of its staff, the Institute enjoys a close working relationship with architects, engineers, code officials and educators who recognize its professional status in the fields of specification writing, structural research, design development and performance standards.

AISC represents the total experience, judgment and strength of the entire domestic industry of steel fabricators, distributors and producers. The scope and success of its activities could not be achieved by any one member of the industry. The nation shares the rewards of these activities – through better, safer and more economical buildings, bridges and other structures framed in structural steel.
