Abstract

In order to explore the calculation method of torsional bearing capacity and hysteretic behavior of steel reinforced concrete columns with welded studs (SSRC) columns under the combined action of compression, bending, shear and torsion, the quasi-static loading tests of 12 SSRC columns and 1 control column were designed and completed with the parameters of steel ratio, longitudinal reinforcement ratio, volume stirrup ratio, stud spacing and stud position. The failure modes of the specimens were observed, and the seismic performance indexes such as hysteresis curve, skeleton curve, bearing capacity, energy dissipation and deformation performance of each specimen were obtained. The influence of different parameters on the above indexes was analyzed, and the calculation formula of torsional bearing capacity of this kind of members was proposed. The results show that the variation parameters have little effect on the failure mode of the specimens, and all the specimens show obvious bending and torsion failure. The torque-torsion angle hysteresis curve of the specimen has obvious pinching phenomenon, which is shown as an inverse 'S' shape, but the bending moment-displacement hysteresis curve is relatively full, which is shown as a spindle shape. The steel ratio and stirrup ratio have little effect on the torsional and flexural capacity of SSRC columns. The longitudinal reinforcement ratio and stud spacing have a great influence on the torsional bearing capacity of SSRC columns, and the maximum increase is 12.29% and 18.92% respectively, but the influence on the flexural bearing capacity of SSRC columns is not significant. Welded studs can significantly enhance the ductility and energy dissipation capacity of steel reinforced concrete columns. Considering the seismic indexes such as bearing capacity, energy dissipation and ductility, it is recommended to use X-type welding for studs. Finally, a practical formula for calculating the torsional bearing capacity of SSRC columns is proposed. The calculated results are in good agreement with the test results.
