Abstract: The third phase of Nanjing Xinjiekou department store tower is constructed on the eighth floor of its second phase,  which is designed according to the' 89'  series standard. Because of the increase of total height and gross area after subsequent construction, the difference between two designs carried out by different standard, and the request for ultra limited high-level earthquake-resistance performance design, the core tube, the constructed frame column and the beam column node must be reinforced. Emphasize the design principle, goal and method of the reinforcement for column, the beam column node and the core tube for the above reasons.
