摘要: 廣州科學(xué)城超限高層塔樓為 A 級(jí)高度的連體結(jié)構(gòu),存在扭轉(zhuǎn)不規(guī)則、凹凸不規(guī)則、復(fù)雜連接的不規(guī)則情況。設(shè)計(jì)中采用了基于性能的抗震設(shè)計(jì)方法,根據(jù)結(jié)構(gòu)的重要性提出不同的抗震性能目標(biāo),并對(duì)結(jié)構(gòu)進(jìn)行小震彈性分析、小震彈性時(shí)程分析、中震性能設(shè)計(jì)、大震等效彈性分析及動(dòng)力彈塑性時(shí)程分析。 分析結(jié)果表明,結(jié)構(gòu)整體和各構(gòu)件的抗震性能均能達(dá)到預(yù)期目標(biāo)。 對(duì)于連接體結(jié)構(gòu),通過(guò)補(bǔ)充分析及多種構(gòu)造措施加強(qiáng),確保連接體結(jié)構(gòu)構(gòu)件滿足設(shè)定的抗震性能目標(biāo)。

Abstract: Over-limit high-rise towers building of Guangzhou Science City is linked with connective structures with A-levelrequirement of height. There are irregularities including irregular torsion, irregular bumpsand and complex connection. Theperformance-based seismic design method was adopted in the design. Different performance targets were proposed accordingto the importance of the structure. The elasticity analysis under frequent earthquakes, the elastic time-history analysis underfrequent earthquakes, the performance design under fortification earthquakes, the equivalent elasticity analysis under rareearthquakes and elastic-plastic time-history analysis were performed. The analysis results show that the seismic performanceof the whole structure and each component can reach the expected target. For connective structures, the supplementarycalculation and analysis and various structural measures were used to strengthen the components of connective structures toensure that all components meet the expected seismic performance targets.

Keywords:over-limit high-rise building; tower linked with conjoined structure; plane oblique; performance-based seismicdesign; dynamic elastic-plastic analysis
