［摘要］盛京金融廣場項目T2塔樓主體結(jié)構(gòu)高度為298-89m，采用框架-核心筒組合結(jié)構(gòu)體系。結(jié)構(gòu)初步設(shè)計階段進行了核心筒內(nèi)墻不均勻布置、均勻布置，環(huán)向桁架方案、有限剛度加強層方案對比。結(jié)構(gòu)彈塑性性能分析表明，結(jié)構(gòu)設(shè)計時應(yīng)重視框架二道防線作用、地震作用下的類共振反應(yīng)等。本工程方鋼管混凝土柱根據(jù)最新試驗進展、理論研究成果進行設(shè)計，采取了高于規(guī)范要求的安全措施。

Abstract:T2 tower of Shengjing Financial Plaza Project with height of 298-89m adopts frame-corewall composite structural system. In the preliminary design stage of the structure, different schemes were compared including the corewall scheme with unevenly distributed inner wall, the corewall scheme with evenly distributed inner wall, ring truss scheme and the strengthened story scheme with limited rigidity. The elastic-plastic performance analysis of the structure shows that in the structural design, attention should be paid to the action of two lines of defense and resonance-like response under earthquake action. The concrete-filled square steel tubular column of the project was designed according to the latest experimental progress and theoretical research results, and safety measures higher than the requirements of the code were taken.
Keywords:Shengjing Financial Plaza; frame-corewall; strengthened story with limited rigidity; resonant-like response of earthquake action; elastic-plastic analysis; concrete-filled square steel tubular column
