Abstract

Abstract

In recent years CFRP is widely applied to the field of rehabilitation and retrofit of existing structure, which can effectively confine the deformation of the concrete so that the carrying capacity and ductility capability of the structure are increased remarkably.The uniform calculation formula of the conversion volume stirrup rate of CFRP is given.Based on the relevant design specifications.The basic calculation method of seismic strengthening for reinforced concrete columns is introduced, and calculation flow chart of seismic strengthening is designed and software design by Visual Basic is also realized.CFRP seismic strengthening design interface and calculation method of columns of Southeast University Deep Strengthening Soft System(SEU_DEEP) are introduced and one practical example is presented to illuminate in detail.
