In a complex high-rise concrete structure design, concrete frame column may become short column.The stiffness of reinforced concrete short column is larger than ordinary concrete column. Under earthquake excitation,the short column shares more earthquake action, and its deformation capacity and energy dissipation ability is poor,at last the short column presents shear failure.In this paper, we analyze the seismic performance of high-rise frame-shear wall structure and high-rise frame-shear wall
