［摘要］京東集團(tuán)西南總部大廈是存在平面不規(guī)則、豎向不規(guī)則等多項(xiàng)超限情況的復(fù)雜高層建筑。介紹了項(xiàng)目的結(jié)構(gòu)形式和設(shè)計(jì)難點(diǎn)，針對結(jié)構(gòu)的超限項(xiàng)采取了合理調(diào)整結(jié)構(gòu)剛度分布、墻內(nèi)設(shè)置型鋼、核心筒全高設(shè)置約束邊緣構(gòu)件、樓板開洞區(qū)域增加板厚及配筋等設(shè)計(jì)措施，并對結(jié)構(gòu)關(guān)鍵部位采用抗震性能化設(shè)計(jì)。采用PKPM，ABAQUS軟件對結(jié)構(gòu)進(jìn)行計(jì)算分析。結(jié)果表明，結(jié)構(gòu)周期比、最大層間位移角、層間剛度比、大跨懸挑區(qū)域節(jié)點(diǎn)驗(yàn)算等均滿足規(guī)范要求，驗(yàn)證了結(jié)構(gòu)體系的合理性。

Abstract:Southwest Headquarters Mansion of JD.com is a complex high rise building with many out-of-code factors including irregular plane and vertical irregularity. The structural form and design difficulties were introduced. Out-of-code structural issues were analyzed and design measures were taken including reasonable adjustment of structural stiffness distribution, setting section steel in walls, full height setting confined boundary elements in corewalls, strengthening the slab thickness and reinforcement in floor opening areas, and seismic performance design for key parts of the structure. Through calculation and analysis of the structure by using PKPM, ABAQUS software, results show that, structure period ratio, maximum interlayer displacement angle, interlayer stiffness ratio, joint check of large-span cantilever area meet the requirements of the code, thus validating the rationality of the structural system.
Keywords:complex high rise building; out-of-code measure; seismic performance design
