Abstract:There are practical difficulties in the design and construction process of the modeling tower on roof of a high-rise office building in the Chinese northwest region. With full understanding of architectural modeling creativity at the same time, mechanics was cleverly used as well as construction details of the installation. The structural safety was ensured and the steel tower structure was optimized. The steel consumption in the final adopted optimization scheme is only 1/20 of the original steel tower scheme, which achieved a good optimization effect.

Keywords:steel structure; recycle action; installation in high position; construction period; cost
