| 因建筑造型所需，针对淄博明发世贸中心大厦超高层建筑顶部造型的收进方案进行比选。介绍了四种常用的建筑造型结构收进处理方式，主要分析其中两种收进方式（转换块收进、斜柱挑梁收进）的节点受力，重点介绍了两种收进方式节点的传力路径、应力、变形等力学特征，并对两种收进方式进行了整体计算参数分析。结果表明，斜柱转换对相关水平构件产生的力仅为转换块产生水平力的24.62%，转换块收进产生的应力集中现象远大于斜柱收进，对于转换块收进采用加腋措施后应力集中现象仍然较为明显。斜柱收进对结构整体受剪承载力、整体刚度影响并不大，转换块收进则有明显的受剪承载力突变现象。两种收进方式对整体倾覆力矩均无较大影响。最后该工程选用斜柱收进方式，并对整体结构进行抗震分析、结构设计。 |

| Considering the aesthetics in architecture，the setback schemes for the rooftop of Zibo Mingfa Trade Center Building are compared. Four common structural setback methods are introduced，and two of them （conversion block setback and inclined column setback） are analyzed from the mechanical performance and characteristics，which includes the force transmission path，stress， and deformation of the joints，as well as the overall calculation parameters. The results show that the force generated by the inclined column conversion on the relevant horizontal members is only 24. 62% of the horizontal force generated by the conversion block，and the stress concentration caused by the conversion block is much larger than that of the inclined column，and is still obvious after the axillary for the conversion block setback. The inclined column setback has little effects on the shear bearing capacity and overall stiffness of the structure，while the conversion block setback has obvious sudden changes in the shear bearing capacity. The two schemes have no significant influence on the overall overturning moment. Finally，the project adopts the inclined column setback scheme，and the seismic analysis and structural design of the structure are carried out. |
