Abstract:: To explore the effect of torsion on the progressive collapse resistance of RC frame, a finite element model was established by LS-DYNA. Based on the reasonable verification of the torsion tests of beams and the antiprogressive collapse tests of frames, the influence mechanism of torsion on the progressive collapse resistance of the 2-D frame was studied, and the anti-collapse performance of the spatial frame was analyzed. The results showed that compared with non-torque members, when the initial torque reached 20%, 40%, 60%, and 80% of the torsional resistance of the beam, the compressive arch action capacity decreased by 0. 5%, 3. 4%, 10. 9%, and 15. 6%, respectively. With the increasing torque, the fracture of the beam bottom reinforcements showed a trend of advancing and then delaying. While the fracture of the beam top reinforcements near the middle column kept advancing. The coordinated torsion caused by transverse beam bending in the spatial frame would make the bottom reinforcements fracture earlier than the planar frame. The collapse resistance of the spatial frame was equal to the superposition of the capacities of its corresponding planar frame and transverse beam before the reinforcements fracture.
