The building is divided into two towers of East and West in 23rd story, and two towers merge in 26th story, and it is a complex high-rise building. Structural seismic effects are reduced and ductility is improved as well as energy dissipation capacity to fulfill the requirements of “not collapse under rare earthquake” according to the following measures, such as optimization of the structure and component arrangements, reasonable selection of energy dissipation components and light building materials, and adoption of performance based seismic design in key and weak parts with targeting strengthened measures.Keywords: braced-frame structure; buckling restrained brace; conjoined structure; performance based seismic design作者簡(jiǎn)介：楊聰武，一級(jí)注冊(cè)結(jié)構(gòu)工程師，Email：kgjtycw@126.com。參考文獻(xiàn)［1］中國(guó)建筑科學(xué)研究院PKPM CAD工程部. 多層或高層建筑結(jié)構(gòu)空間有限元分析與設(shè)計(jì)軟件（墻元模型）SATWE（2010版）［M］. 2011.［2］上海市金屬結(jié)構(gòu)協(xié)會(huì)，同濟(jì)大學(xué)多高層鋼結(jié)構(gòu)及鋼結(jié)構(gòu)抗火研究室.
