Abstract:In the retrofitting of Nanjing Central Hotel, new concept of design was brought in, which enclosed the outdoor semi-circle shaped courtyard into a nine-story large sharing space. However, the concept was very difficult to be carried out. In the new-added steel structure, load-transferring was very clear, and self-weight was reduced to the minimum. Many design difficulties were solved such as damping ratio setting and coincident work of adding stories with the old structure. The structure aesthetics and the operation feasibility in downtown were well taken into consideration. The project was carried out smoothly, and it achieved great economic and social benefit.
Keywords:adding story; steel structure; seismic effect; damping ratio
