［摘要］贵阳渔安安井温泉旅游城未来方舟G7为大型商住综合体项目，塔楼与商业裙楼设缝分开。其中裙房采用框架结构，共7层，3栋塔楼为高度180～210m的超高层住宅，采用框支剪力墙结构。塔楼由于高位转换且转换层以上层数较多，结构受力相对复杂。采用ABAQUS对框支转换构件进行三维实体有限元分析，揭示框支转换结构“拉杆-拱”受力机理；通过改变转换层位置，研究框支剪力墙与落地核心筒之间的剪力传递规律；提出两种方便转换梁拉筋贯通锚固的框支转换节点形式，并论证其安全可靠性。对转换梁、框支柱、框支连接节点、框支剪力墙、落地核心筒以及转换层上下几层楼盖等转换结构相关构件进行分析，并采取相应构造加强措施，保障转换结构受力安全，使得整体结构达到预设的C级抗震性能目标。

Abstract:Guiyang Yu′an Anjing Hot Spring Tourist City Future Ark G7 Building is a large-scale commercial and residential complex project where the tower and commercial skirt building are separated with construction joints. The skirt building adopts frame structure with seven stories. Three tower buildings are super high-rise residential buildings with height of 180~210m, and frame-supported shear wall structure is adopted. Because of the high-level transfer and the large number of stories above the transfer floor, the structural stress of the tower building is relatively complex. ABAQUS was used to carry out three-dimensional solid finite element analysis of frame-supported transfer members to reveal the pulling rod and arch mechanical behavior of frame-supported transfer structure. By changing the location of transfer floor, the shear transfer law between frame-supported shear wall and corewall on the ground was studied. Two types of frame-supported transfer joints were proposed to facilitate the anchorage of transfer beam tension bars. Its safety and reliability were also demonstrated. Members related to the transfer structure were analyzed including the transfer beam, frame-supported column, frame-supported connection node, frame-supported shear wall, corewall on the ground and the upper and lower floors of the transfer layer, and corresponding structural strengthening measures were taken to ensure the safety of the transfer structure, so that the overall structure could reach the pre-set C-grade seismic performance target.

Keywords:super high-rise building; frame-supported shear wall structure;  pulling rod and arch mechanical behavior; shear transfer; frame-supported transfer joint
