Fire Response Analysis of Circular Concrete Filled Tubular Columns and the Effects of Axial and Rotational Restraints

Abstract

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.
