［摘要］中山古鎮(zhèn)燈都商廈呈傳統(tǒng)油燈狀，其體形凹凸變化十分突出，采用單一的結(jié)構(gòu)體系很難滿足抗側(cè)剛度的全樓均勻性，給結(jié)構(gòu)設(shè)計(jì)造成了非常大的挑戰(zhàn)。為此，結(jié)合工程本身的外形變化特性，結(jié)構(gòu)設(shè)計(jì)上采取了多種結(jié)構(gòu)體系相結(jié)合的方法，根據(jù)不同平面尺寸對(duì)整體剛度的影響以及各種體系對(duì)抗側(cè)剛度的貢獻(xiàn)，交替采用了多種結(jié)構(gòu)體系，以保證體形復(fù)雜的結(jié)構(gòu)在抗側(cè)剛度上的均勻性。工程利用巨型斜置鋼管混凝土柱、內(nèi)置鋼管混凝土剪力墻、鋼結(jié)構(gòu)桁架、跨樓層交叉撐、加強(qiáng)層等關(guān)鍵技術(shù)組成了剛度、延性和穩(wěn)定性均良好的結(jié)構(gòu)體系，有效解決了剛度突變、整體傾覆、中部球狀大懸挑等難點(diǎn)，對(duì)各構(gòu)件交叉、樓層轉(zhuǎn)換等關(guān)鍵點(diǎn)均采用了針對(duì)性措施，確保工程安全和有效實(shí)施。

Key technologies of super high-rise and complicated shape structure design in Zhongshan Guzhen Light Capital Mansion

Abstract:The shape of Zhongshan Guzhen Light Capital Mansion looks like a traditional kerosene light, which brings much challenge to the structure design. A single structural system is difficult to meet the lateral stiffness uniformity of the entire floor, many structure systems are adopted to keep the uniformity of stiffness. In the project, those key technologies, including huge slanting steel tube concrete column, concrete shear wall enveloped by steel plate, steel truss, across brace, strengthen story with outriggers etc., were used, leading to a good structural system in stiffness, ductility and stability. Furthermore, the structural system alters at different height thus the structural design’s difficulties in abrupt change in rigidity, overturning and overhanging in sphere shape at middle height were all solved effectively. To guarantee the safety and economy, optimization was performed after many cycles calculation.

Keywords:complicated shape; super high-rise structure; huge slanting steel tube concrete column; concrete shear wall enveloped by steel plate; across brace; stiffness mutation; overturn
