RESPONSE OF REINFORCED PRESTRESSED CONCRETE BOX STRUCTURES TO DYNAMICALLY APPLIED TORSION/

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