DESCRIPTION:Noémi Friedman\, Associate Lecturer at the Ybl Miklós Facult
 y of Architecture and Civil Engineering of Szent István University (Hunga
 ry)\nThe specific cylindrical system\, namely the deployable antiprismatic
  lattice structure\, derived from the yoshimura origami pattern and propos
 ed by Hegedűs\, is characterized by its pop-up deployment due to the ener
 gy accumulated from lengthening some bars during packing. Zero deployment-
 load corresponds both to the fully deployed and the compact configuration\
 , the latter being an unstable equilibrium state corresponding to the maxi
 mal internal energy. The packing behavior of the antiprismatic deployable 
 structure will be shown through a simplified 2D structure possessing simil
 ar packing properties to that of the chosen specific system. The equilibri
 um paths of packing and the concerning difficulties (bifurcation of the pa
 th\, snap-back phenomenon\, singular configurations etc.) as well as the p
 acking sequences will be revealed through analytical and numerical researc
 h.
