| 摘 要： | 当前，随着国家经济的快速发展、人民生活水平的不断提高、城市地价的日益昂贵，高层建筑得到了迅速发展.在高层建筑中，由于柱轴力，特别是中下部各层柱的轴力比较大，而实际工程中又多采用普通强度的混凝土，因此，为满足轴压比限值的要求，在钢筋混凝土高层设计中经常出现短

| Abstract: | The bearing performance of nine reinforced concrete short columns under cyclic loading was tested.The experi- mental results show that the new method of using continuous carbon fiber sheet(CFS)on strengthening reinforced concrete short columns can increase their shear strength and improve their deformation capability and ductility.At the same time,the factors affecting the effectiveness of seismic strengthening of reinforced concrete short columns,such as the shear span rati- o,axial compression ratio,tensile strength of CFS,the number of CFS layers and concrete strength are analyzed. |
