［摘要］某項(xiàng)目平面為凹凸不規(guī)則的“凹”字形平面，在結(jié)構(gòu)頂部布置了連接體，并與主體結(jié)構(gòu)剛接。分析了連接體對(duì)整體結(jié)構(gòu)的影響，并對(duì)與主體結(jié)構(gòu)剛接的連接體及相關(guān)范圍進(jìn)行了中震和大震性能化設(shè)計(jì)，最后對(duì)連接體進(jìn)行了動(dòng)力分析。分析結(jié)果表明，連接體對(duì)主體結(jié)構(gòu)的影響較小，關(guān)鍵構(gòu)件截面和配筋適宜，滿足性能設(shè)計(jì)的要求；安裝調(diào)諧質(zhì)量阻尼器TMD后連接體的動(dòng)力反應(yīng)滿足要求。

Abstract:The plane of a project is a concave-shaped irregular plane, with connecting body arranged at the top of the structure to connect with the main structure in a rigid connection way. The influence of the connecting body on the whole structure was analyzed, and performance-based seismic designs were conducted on connecting body to the main structure and relevant range under fortification and rare earthquakes. Finally, the dynamic analysis of the connecting body was carried out. The analysis results show that the influence of the connecting body on the main structure is small, and the key cross section and reinforcement of the key components are suitable to meet the requirements of performance design. The dynamic response of the connecting body meets the requirements after the installation of tuned mass damper（TMD）.

Keywords:plane irregularity; high-position connecting body; performance-based design; key component; dynamic analysis; TMD
