Abstract:
The torsion effect of L-shaped column under low cyclic loading was discussed based on the experiment. The bearing capacity calculation method of shear and torsion of component under combined forces was gained by referring to standard, at the same time, the influence of additional torque to L-shaped column was quantitatively analyzed. The result shows that the torsion performance in single L-shaped column is different with that in column frame; the former is sensitive to loading angle of horizontal load, and its additional torque influence can not be ignored under asymmetric loading, meanwhile, the composite action of bending, shear and torsion in design should be considered in terms of the re-torsion capacity of latter, as a part of the structure that works together is advanced obviously.
