[摘要]通過對一個81-9m大跨度鋼結(jié)構(gòu)連體與其兩端主樓不同連接方式的特點及兩端主樓具體情況進(jìn)行分析,確定連體與其兩端主樓采用弱連接方式;根據(jù)連體功能要求及平立面布置情況,確定連體采用鋼桁架結(jié)構(gòu)形式;通過對連體兩端主樓進(jìn)行大震作用分析,確定連體支座具體設(shè)計參數(shù),并通過采用TMD系統(tǒng)對連體進(jìn)行減振優(yōu)化設(shè)計,解決了連體在人行荷載下的共振問題。

Abstract:By analyzing the characteristics of different connection modes of an 81-9m large-span steel connected structure and its main buildings at both ends, and analyzing the specific conditions of the main buildings at both ends, it was determined that a weak connection mode was adopted to the connecting body and the main buildings at both ends. According to the requirements of the connected body function and the flat facades in the layout, it was determined that steel truss structure was used for the connected body. Through the analysis of the main buildings at the two ends of the connected body under the rare earthquakes, the specific design parameters of the connected bearing were determined, and the vibration-damping optimization design of the connected body was implemented using the TMD system to solve the problem of resonance of connected body under human loads.
Keywords:steel connected structure; bearing design; large\|span; tuned mass damper
