| Abstract: | In order to study the calculation method of torsional bearing capacity of welded stud steel reinforced concrete(SRC) columns under combined compression, bending, shear and torsion forces, based on the hysteretic test results, the test process and failure mode are analyzed. Using the space truss theory and superposition principle, the torsional bearing capacity calculation model and unified strength equation of welded stud SRC columns are proposed. The results show that the calculation results of the proposed unified strength equation and torsional bearing capacity calculation method are in good agreement with the test results, and the mean error of the calculation results is within 3%. |
