“…Authors as Wang [16] [17] [18], Leskela [19], Aribert et al [20], Ribeiro et al [21] and Espinos et al [22] [23] have focused on the study of the simple calculation model in EC4 (option b). Because of the complexity of the specific method in Annex H and after having been proved that it produces unsafe results for slender columns [16] [20], authors are more inclined to follow the general principles in Clause 4.3.5.1, which cover all types of composite columns.…”

“…ii) Clearly depicted in [70] by Espinós et al, the second approach has been widely studied by researchers such as Wang and his co-workers [71][72][73] as well as many researchers in Europe. [74][75][76]. The method consists of applying reduction coefficient to the mechanical properties of the concrete and steel assembling the CFT as a function of the fire loading and thus, using similar verifications as for the case of the resistance of the members (cross-sectional and buckling verifications).…”

The vulnerability of framed structures has been analyzed until recently from two different perspectives: Structural and socio-economical. For the sake of assessing the former, indexes and objective measurements have been proposed in the literature. These indexes include relatively accurate assessments of the strength, ductility, energy absorption, fire, blast response and resilience of the elements in order to define a higher-level structural magnitude. Similar approaches are performed with the latter when it comes to assessing damage, economical aspects, social and other important factors. On the other hand, concrete-filled tubes (CFT) have proven structurally efficient due to their relatively high strength-toweight ratio. Considerably complete state-of-the-art reviews are available for these members when it comes to analyzing their strength and overall or local buckling in static and/or dynamic responses. Reviews concerning important issues related to the structural vulnerability of those members are, however, scarce. In this paper, a state-of-the art dealing with the behavior of concrete-filled tubes is presented. The novelty of such approach is to present research concerning CFT but, in this case, from a structural vulnerability perspective (not socioeconomical), that is to say, summarizing references concerning seismic response, fire resistance, impact response and other main characteristics that are further used when defining the aforementioned indexes. Relevant numerical, experimental and theoretical studies presented in recent years are pinpointed as well as potential research trends.

“…As a consequence of these results and provided that the specific method for CFT columns was tedious to apply in spite of its assumed simplicity, the trend followed by most researchers (Wang 1997b, Wang & Orton 2008, Aribert et al 2008, Ribeiro et al 2008, Leskela 2009) has been to resort to the general approach of Eurocode 4 Part 1.2, but as it has been exposed just few researchers have taken a further step to investigate the applicability of this general method specifically to CFT columns (Wang 1997, Aribert et al 2008).…”

for their indispensable support and guidance during my doctoral period. Thanks to their confidence, the development and consecution of this thesis have been possible.I also wish to show my gratitude to my colleagues from Universitat Politècnica de València for the comforting moments which relieved the pressure of this constant work: Ana, Andrés and Toni, thanks for maintaining the same good atmosphere at the office as always. And thanks to the people from the Department of Construction Engineering and Civil Engineering Projects with whom I shared my beginnings: Héctor, Estefanía, Josemi, José Vicente, Juan and Vicente. Special thanks go to Ana Espinós for her wise advice in my first approach to concrete filled tubular columns and in every aspect of my career.Sincere gratitude goes to my new colleagues from Universitat Jaume I for their constant support even in the distance, especially to David and Roberto who have made easier this hard period.Another big thank you goes to Dr. Filippou for inviting me to join a leading institution as University of California at Berkeley during part of my doctoral period and for his assistance during my stay there since I had the incredible opportunity of collaborating and attending the master lectures of a referent in the field of nonlinear analysis of structures. I would like also to thank the encouragement received from all my friends during these years.Last of all, I would like to give special thanks to my family, in particular to my grandparents, parents and brother for their patience and understanding. This thesis has been possible thanks to you.
