Response of reinforced/prestressed concrete box structures to dynamically applied torsion Original Research Article

Inelastic dynamic response of reinforced/prestressed concrete box structures to torsion is investigated in this article. To perform this research, three items need to be critically studied. (1) The primary curve (torque-twist curve), (2) the torsional hysteretic rules and (3) a dynamic model. The inelastic dynamic response analysis of both reinforced and prestressed concrete box structures (such as: spent fuel pools, storage tanks, containments and building cores, etc.) under torsion can be completed by the proposed method. The research findings in this article can be applied to box structures in nuclear power plants.
