［摘要］華潤深圳灣總部大樓采用密柱外框筒+勁性鋼筋混凝土核心筒結(jié)構(gòu)體系，通過斜交網(wǎng)格柱在高區(qū)和低區(qū)加強(qiáng)形成密柱外框筒，形成了可靠的二道防線；提出了新型外框偏心節(jié)點(diǎn)，研究了偏心節(jié)點(diǎn)受力性能和其對整體結(jié)構(gòu)的影響，實(shí)現(xiàn)了建筑的無柱空間要求；高區(qū)核心筒采用新穎的斜墻收進(jìn)方案，既滿足了建筑的使用功能，也保證了結(jié)構(gòu)傳力的安全有效性，避免了剛度的突變。比較分析了伸臂阻尼器數(shù)量對舒適度的影響，確定了經(jīng)濟(jì)有效的一道伸臂阻尼器形式。此外對總體結(jié)構(gòu)進(jìn)行了大震彈塑性計(jì)算分析，有力地保證了工程的安全性、合理性。

Abstract:The main structural system for Shenzhen Bay Headquarters Building of China Resources Group consists of close-column outer frame tube and steel embedded RC corewall structural system. There are staggered grids in both high and low zones to strengthen the building to form close-column outer frame tube as a reliable second seismic fortification line. A new type of eccentric outer frame joint was proposed. Its mechanical performance and impact on the whole structure were studied to realize architectural requirement of column-free space. A novel scheme of step-back inclined shear walls was adopted in the high zones of the corewall to realize service function of the architecture and guarantee safety and effectiveness of structural force transmission. This can also avoid stiffness mutation. The influence of the number of outrigger dampers on comfort was compared and analyzed, and an economical and effective form of one outrigger damper was determined. In addition, the calculation analysis was carried out on elasto-plasticity of the overall structure under large earth, which effectively ensured the safety and rationality of the project.
Keywords:Shenzhen Bay Headquarters Building of China Resources Group; super high-rise building; staggered grid; close-column outer frame tube; step-back inclined shear wall; eccentric outer frame joint; outrigger damper
