【摘要】 出版大厦为框架-双核心筒结构体系，采用YJK、ETABS软件对主体结构进行整体计算对比分析。为了满足建筑功能，针对结构的局部转换提出了3种解决方案，并分别通过有限元软件ABAQUS进行转换区3层框架力学性能分析。结果表明：结构在风荷载或地震作用下，主体结构不仅具有很好的抗震性能，而且能满足较好的经济性；局部转换最终采取斜柱转换方案；斜柱转换在竖向荷载的作用下，受力更加均匀，减少了结构节点区域的应力集中现象；在竖向荷载和水平荷载的共同作用下，由于斜柱对框支柱的支撑作用，转换结构的压应力区域由框支柱与水平梁连接处转移到斜柱与框支柱连接处，使整体性更加稳定，为项目结构设计方案选择决策提供参考。更多还原

【Abstract】 Publishing Building is a frame-double core tube structure system, and YJK and ETABS software were used to carry out overall calculation and comparison analysis of the main structure. In order to meet the building function and lead to the local transformation of the structure, three solutions were proposed, and the mechanical properties of the three-story frame in the transformation area were analyzed by the finite element software ABAQUS. The results show that under the action of wind load or earthquake, the main structure not only has good seismic performance, but also can meet the better economy. The local conversion finally adopts the inclined column conversion scheme. Under the action of the vertical load, the force of inclined column conversion is more uniform, reducing the stress concentration phenomenon in the structural node area. Under the combined action of vertical load and horizontal load, due to the supporting effect of inclined column on frame pillar, the compressive stress area of transfer structure is transferred from the connection between frame pillar and horizontal beam to the connection between inclined column and frame pillar, which makes the integrity more stable and provides reference for the selection and decision of project structure design scheme.更多还原
