Austenitic stainless steel is an excellent construction material for structures required to withstand accidental loads such as seismic and/or fire events due to its appropriate mechanical properties, including high ductility, considerable strain hardening and good fire resistance. In recent years, a considerable amount of research has been devoted to the understanding of the structural performance of single isolated stainless steel members. However, new trends in the design philosophy moving from current member-based methods to direct system-based approaches will require more experimental evidence on more complex structural systems such as frames, which are currently scarce. With the aim of contributing to the advances in this field, one of the first known extensive experimental programmes on austenitic stainless steel frames is presented in this paper. The experimental programme comprised several sub-programmes, in which the performance of stainless steel structures at different levels was investigated. This paper describes a series of tests on austenitic stainless steel cross-sections and members, which were utilized in the planning and analysis of the subsequent frame tests. The paper also outlines the complex experimental set-up adopted for the stainless steel frame tests, including the implemented loading schemes, auxiliary elements and instrumentation, through a detailed explanation of the different issues encountered in the process of their definition. The knowledge gained and the experiences reported in this paper could assist researchers in planning similar experimental programmes., "This experimental programme was developed in the frame of the Project BIA2016-75678-R, AEI/FEDER, UE “Comportamiento estructural de pórticos de acero inoxidable. Seguridad frente a acciones accidentales de sismo y fuego”, funded from the MINECO (Spain). The financial support received from the European Commission and Spanish Ministry for Science, Innovation and Universities through the Marie Sklodowska-Curie grant agreement No. 842395 and the FPI-MINECO PhD fellowship Ref. BES-2017-082958 is also gratefully acknowledged. Authors would like to acknowledge the support, advice and suggestions from Professor K. Rasmussen (The University of Sydney), Professor B. Young (Hong Kong University) and Professor L. Gardner (Imperial College London) in the preparation of this experimental programme, and the support from Acerinox and MeKano4. The time and effort from the staff at the Laboratory of Technology of Structures and Materials and the Geotechnical Engineering and Geosciences Department from Universitat Politècnica de Catalunya are also much appreciated.", Peer Reviewed
