[摘要] 在石油化工设计中，常会出现设备高度高于或等于支撑框架的情况。通过工程实例，介绍了柱子直接落在转换梁上的转换结构的设计；讨论了判断转换结构侧向刚度的公式；阐述了如何采用逐级放大地震作用的方法推断结构的抗震性能，可为类似工程的设计作参考。

Abstract: In the petrochemical project design, it is usually found that the equipment's height is higher or equal than the height of the frame which is supporting the equipment. As the actual project example, how to design the columns, which are directly settled on the transfer beam, and the design parameter of the transfer storey are introduced. The difference of the formula which is calculated the side stiffness of the transfer storey is discussed. And it is discussed how to gradually amplify the effect ofthe earthquake to confirm the earthquake-resistant behavior of the structure. It may be referred to the similar project.
Keywords: transfer storey; transfer beam; earthquake-resistant behavior
