[摘要]南京中心大酒店在加層改造中,將室外半圓形庭院圍合成9層高的超大共享空間,設(shè)計方案新穎,但實現(xiàn)難度很大。結(jié)構(gòu)設(shè)計中為新增鋼結(jié)構(gòu)設(shè)置了清晰的傳力路徑,嚴(yán)格控制結(jié)構(gòu)自重,解決了阻尼比確定、新老建筑共同工作等設(shè)計難題,并兼顧結(jié)構(gòu)美觀和市中心施工可行性,保證了項目的順利實施,取得了很好的經(jīng)濟(jì)、社會效益。

[關(guān)鍵詞]加層;鋼結(jié)構(gòu);地震作用;阻尼比

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
