摘要: 南昌市民中心建筑主要功能為辦公、會議、交易、展覽等,主體采用框架結(jié)構(gòu)體系,存在扭轉(zhuǎn)不規(guī)則、樓板局部不連續(xù)、偏心布置、局部穿層柱、錯層等不規(guī)則項,屬于復(fù)雜超限高層建筑. 采用抗震性能化設(shè)計,使用多種軟件對結(jié)構(gòu)進(jìn)行多遇地震彈性計算和彈性時程分析,進(jìn)行罕遇地震下的動力彈塑性時程分析,并針對超限情況提出針對性的抗震加強(qiáng)措施,分析結(jié)果表明整體結(jié)構(gòu)可以達(dá)到預(yù)定的性能目標(biāo).

Abstract:The main functions of Nanchang Citizen Center are office, conference, trade, exhibition and so on. It adoptsframe structure system, there are some irregular items such as torsion irregularity, partial discontinuity of floor slab,eccentric arrangement, partial through-floor column, split-floor, etc. , belongs to the complex out-of-code high-risebuilding. The seismic performance-based design was adopted, and a variety of software was used to carry out elasticcalculation and elastic time-history analysis of the structure in frequent earthquakes, and dynamic elastic-plastic timehistory analysis in rare earthquakes. In addition, the seismic strengthening measures were put forward according to the outof-code situation. The results show that the whole structure can achieve the predetermined performance objectives.
Keywords:Nanchang Citizen Center; out-of-code high-rise building; seismic performance-based design; time-historyanalysis; seismic strengthening measure
