DYNAMIC RESPONSE OF BOX TUBES TO COMBINED SHEAR AND TORSION

A truss model theory for reinforced-concrete structural walls subjected to static shear was applied to determine the shear-force-displacement relationship as the primary curve for dynamic analysis. The theory is based on equilibrium and compatibility as well as a stress-strain relationship for softened concrete. Similarly, the torque-twist relationship of reinforced-concrete box tubes subjected to static torsion was determined by employing the truss model theory. The authors of this paper predict the inelastic dynamic response of reinforced-concrete box tubes to combined shear and torsion using the primary curve derived from the interaction relationship between shear and torsion, the hysteretic model proposed for reinforced-concrete structures under shear or torsion, and the linear acceleration step-by-step method. Parametric studies are conducted using the proposed algorithms.
