Marian Gizejowski is full professor at the Faculty of Civil Engineering of the Warsaw University of Technology in Poland. His research and lecturing experience includes the position of Postdoctoral Fellow at the University of Sydney in 1983, the Senior Lecturer position at the University of Zimbabwe 1988-1994 and the Associate Professor position at the University of Botswana 2001-2005. He has been invited to become the member of Advisory Boards and Scientific Committees of several international conferences, and to prepare plenary keynote lectures at the conferences taken place worldwide. He has been the author or co-author of several books as well as over 300 journal and conference papers. His research interest is focused on different aspects of structural stability, resistance assessment and codification, as well as on nonlinear analysis and design of steel and aluminum structures. Recently, he has especially focussed on furthering progress in the formulation of stability verification procedures for the application in Eurocodes and the unification of resistance partial factors for their application in different design situations. Jakub Marcinowski is a research professor at Faculty of Civil Engineering, Architecture and Environmental Engineering in University of Zielona Gora, Poland. He obtained his academic degrees at the Technical University of Wroclaw where he was graduated from Faculty of Civil Engineering. He used to work in Iraq at Mosul University (1988/1989) and at Saddam University for Engineering and Science (1989/1990) as an Assistant Professor. The main field of his scientific activity is structural stability phenomena and shell buckling. He is an author or co-author of more than 200 journal and conference papers and other publications. Since 2008 he is a member of Task Working Group TWG8.4 (stability of shells), acting within the European Convention for Constructional Steelwork, ECCS. He is also a member of three Working Groups of European Committee for Standardization acting on amendments to existing European standards. Aleksander Kozlowski is a full professor in Civil Engineering in Rzeszow University of Technology, Poland. He is currently a Head of Department of Building Structures at this University. He previously worked as a visiting professor in Univesidade da Beira Interior, Covilha, Portugal. He has been invited to become the member of Advisory Boards and Scientific Committees of several international conferences, such as Eurosteel, and took part in few European Projects, such as Cost, Robust, Android, Affordable House and Purest. He has been the author or co-author of over 200 journal and conference papers and several technical books. His recent investigations focus on steel and composite joints and their influence on structure behavior. Jerzy Ziolko is emeritus professor of the Faculty of Civil Engineering and Environment of the Gdansk University of Technology. He was granted the honorable distinction of the Doctor of Honoris Causa in 2012 by the University of Technology and Life Sciences in Bydgoszcz, Poland. Professional and research interests of Professor Jerzy Ziolko focus on different structural and technological aspects of metal building and civil engineering structures, mostly steel shell structures (tanks for liquids and gases), durability and safety of steel structures, rheological aspects of mechanical properties of steel due to long-lasting exploitation and methods of modern assembly, maintenance and restoration of steel structures. Professor Ziolko has published 14 books (including 4 authored individually) and 213 chapters and journal articles (including 39 in foreign journals). He is a member of Editorial Board of the journal Steel Construction - Design and Research. He has been invited to become the member of Advisory Boards and Scientific Committees of several international conferences, and to prepare plenary keynote lectures at the conferences taken place worldwide.
