| Steel reinforced concrete special-shaped column is a new structural form. It has all strongpoints of steel reinforced and special-shaped column structure.Bearing capacity and ductility of this new structure is very good, as well as excellent applicable quality and pleasing to the eye. Based on the experiment of 4 steel reinforced concrete of L-shaped section columns subjected to low cyclic reversed lateral loads, the main failure patterns of steel reinforced concrete of L-shaped section columns under compression, combining flexure and shear force are obtained, and then the load-deflection P-D hysteretic loop of all the specimens have been drawn. The ductility coefficientμand equivalent viscous damping coefficient h_e have been calculated. The influence of axial comperesion ratio,shear span ratio, and stirrup ratio on the hysteretic loop, capacity of energy dissipating and ductility of steel reinforced concrete special-shaped column are analyzed.Its have been contrast with each other reinforced concrete special-shaped column and steel reinforced concrete special-shaped column. Test results indicate that steel reinforced special-shaped column have the behavior of high resistant capacity and excellent ducitility, the seismic performance of which is super to that of reinforced concrete columns.
