Renovation work requires design consideration and invention specific to it, differently from that required for new construction, such as approaches to use the existing building frames so as to reduce the amount of additional members to use, or work methods and execution consideration to minimize noises and vibration. One of the cases described is a renovation work of a tall building which achieved an enhancement in seismic resistance by avoiding removal of existing members and frames or addition of new members wherever possible but instead, installing viscoelastic dampers into the connections between existing brace members, thereby improving the damping performance of the building. The other case is about a tall building which increased its seismic energy absorption capacity by replacing existing braces with buckling restrained braces. This work adopted a bonding work system using epoxy resin so that a minimum of noise and vibration would be caused at the connections between the damping braces and the existing building structure. Each of the cases described in this paper is a successful project in effectively improving the seismic resistance of an existing tall building. It can be expected that these approaches will be applied to renovation cases faced with similar problems in the future.
