Dans le cadre de la thèse on a analysé également les caractéristiques mécaniques d’une système différent de la structure d’origine. Pour les deux différent systèmes structuraux on a préparé des modèles physiques expérimentaux, dont les résultat ont conduit aux nouveaux types des structures, lesquelles sont les structures spatiales pliables á plat. On a proposé alors quelques idées et schémas pour la possibilité d’application architecturale de systèmes treillis antiprismatiques. Keywords: deployable structures, transformable structures, antiprismatic, yoshimura pattern In this thesis, an extensive review on different transformable systems used in architecture and civil engineering is given. After the review, structures undergoing large displacements and instability phenomenon were highlighted.

Budapest, Hungary, H-1111 2 HIGHLY FLEXIBLE DEPLOYABLE STRUCTURES PREFACE AND ACKNOWLEDGEMENT PREFACE AND ACKNOWLEDGEMENT This work presented in this thesis was carried out at the Department of Structural Engineering, Faculty of Civil Engineering, Budapest University of Technology and Economics (BME) and at the Laboratory of Mechanics and Technology (LMT-Cachan) at the École Normale Supérieure de Cachan (ENS de Cachan) in a ‘cotutelle’ program. First I thank both my supervisors Prof. Adnan Ibrahimbegovic and Prof. György Farkas for their constant encouragement and guidance. A debt of gratitude is owed to prof. István Hegedűs for valuable theoretical discussions and guidance. I also would like to express my appreciation to dr. Gyula Greschik and dr. Mihály Weiner for taking their time to help me get along with some difficulties, and for sharing forward- going ideas. I owe a grateful thank to Prof Tibor Tarnai for lending me valuable technical papers and books on the subject and encouraging me to prepare some physical models, and to Flórián Kovács for his profound revision of the thesis and useful advises for correcting. The enormous help of Antal Schuchmann should be also herein acknowledged for his technical support in building the physical models. I would like to thank all of the colleges at the Department of Structural Engineering in Budapest and also the ones at the LMT de Cachan. The parallel doctoral program could not have been carried out without the scholarship received from the French Government through the French Embassy in Hungary, which I would like to herein appreciate. Last but not least, I would like to express my grateful thanks to my parents for their continuous encouragement and support in my whole life without which I could have hardly get to the level where this PhD thesis could be born and acknowledge my family; my husband Gabor Schuchmann and my two beautiful daughters Hanna and Hédi, their continuous love and enormous patience during working on this thesis. This work is connected to the scientific program of the ‘Development of quality-oriented and harmonized R+D+I strategy and functional model at BME’ project. This project is supported by the New Hungary Development Plan (Project ID: TÁMOP-4.2.1/B-09/1/KMR- 2010-0002). 3 HIGHLY FLEXIBLE DEPLOYABLE STRUCTURES DECLARATION DECLARATION The author declares that, except for commonly understood and accepted ideas, or where specific reference is made to the work of other authors, the content of this dissertation are his own work, and includes
