To research the seismic damage assessment mechanism of SRC special shaped column frame joints, the modified Park-Ang seismic damage model was put forward by introducing the combination coefficient based on the mechanical characteristics of special shaped column structures, due to the poor numerical convergence and limited application scope of Park-Ang damage model. The calculation method of combination coefficient for SRC special shaped column frame joints was built according to the measured hysteresis data under low cyclic reversed loading，and the effects of test parameters on the damage evolution of specimens were analyzed. The results show that the damage index calculated by modified Park-Ang seismic model is close to 1.0 in the upper boundary of this model，it meets the numerical convergence better and it is more reasonable in theory. Under the loading angle of 45 °, the damage level of T-shaped column 3D joints is the lowest, while the damage level of cross-shaped column 3D joints is on the contrary. Within certain limits，an increase of axial compressive ratio leads to delay the seismic damage of SRC special shaped column frame joints. There is no noticeable impact of shape steel configuration on the damage of planar joints ； while for 3D joints, the damage level of the specimens configured with channel-shaped steel is higher than that of the specimens configured with T-shaped steel，and the damage level of the specimens configured with empty-web steel is higher than that of the specimens configured with solid-web steel. The damage degree of the specimens formed with L-shaped column is larger than that of the specimens formed with cross-shaped column，while the damage development and accumulation of the specimens formed with cross-shaped column is larger than that of the specimens formed with T-shaped column.

To investigate the hysteretic behavior of welded stud steel reinforced concrete columns subjected to constant axial compression and cycled flexure-shear-torsion, a set of test devices were designed, and nine specimens were prepared for the experimental study. Three parameters, i. e. the welded stud location, spacing and the length of stud were considered in test. The cracks develop progress, failure modes, the flexure-displacement hysteric curves, and torsion-torsion ratio hysteretic curves of welded stub steel reinforced concrete columns under constant axial compression and cycled flexure-shear- torsion were obtained. The effects of these parameters on seismic indexes were discussed, such as failure mode, hysteretic behavior, stiffness degradation, ductility and energy dissipation capacity, and so on. The results show that the failure modes of specimens are torsion-bending failure with torsion cracks, which mainly based on flexural failure. The flexure-displacement hysteretic curves are plump like spindle. The torsion-torsion angle hysteretic curves look like S or Z-shape, which are not so plump. The ductility of specimens weakens under the action of torsion. Welded stud can effectively improve the ductility of the steel reinforced concrete columns, and the smaller the stud spacing, the better the ductility. Staggered welding studs on web and flanges can obviously improve the seismic behavior of specimens. [ABSTRACT FROM AUTHOR]
