Shanghai Shimao International Plaza

PROJECT DESCRIPTION

A series of innovative retrofitting measures are used to achieve the required architectural aesthetics and function. The project introduced energy dissipation devices to avoid having to strengthen most of the structural members. This saved time and construction costs. It also reduced the seismic response of the retrofitted structure back to the original level.

Judge's comment:

The transformation of this commercial building in Shanghai involved a series of innovative retrofitting measures.

To avoid strengthening most of the structural members, energy-dissipation strengthening approaches were used to reduce the structural seismic response via energy dissipation devices: viscous cylinder dampers, viscous damping walls and non-buckling steel plate shear walls in the project, which reduce the seismic response of the retrofitted structure back to the original level.

The judges were impressed by the use of energy-dissipation technology to achieve minimal reinforcement intervention and facilitate refurbishment flexibility, construction convenience and cost savings.
