Steel trusses set in bottom and top of the connected body connect with the tubes at two sides to form a mega frame. The structure scheme of steel trusses was determined through comparative analyses, and the structure was designed according to the concept of performance-based seismic design. The software SAP2000 was used to carry out the elasto-plastic time-history analysis and analysis on the mechanical properties of the steel trusses and tube structure. By shaking table tests and joint tests, the reliability of the structure and joint connections were verified. Relevant seismic strengthening measures were taken based on the calculation analyses and experimental results.Keywords: connected structure; steel truss; shaking table test作者簡介:蘇衛(wèi)東,學士,院副總工程師,教授級高級工程師,一級注冊結(jié)構(gòu)工程師,Email:812282209@qq.com。參考文獻[1]JGJ 3—2002 高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程[S].北京:中國建筑工業(yè)出版社, 2002.[2]GB 50011—2010 建筑抗震設(shè)計規(guī)范[S].北京:中國建筑工業(yè)出版社, 2010.[3]舒云峰,蘇衛(wèi)東,林鋒,等. 重慶西永綜保區(qū)監(jiān)管大樓彈塑性時程分析[J].建筑結(jié)構(gòu),2012,42(S2):107-111.[4]李英民,韓軍,鄭妮娜,等.重慶市西永綜保區(qū)監(jiān)管大樓振動臺試驗報告[R].重慶:重慶大學,2010.[5]李英民,韓軍,齊太陽,等.重慶西永綜保區(qū)監(jiān)管大樓鋼桁架節(jié)點受力性能試驗研究[R].重慶:重慶大學,2012.
