Abstract Research purposes: Through the comparison and analysis of the calculation example，the study is done on the internal force and displacement characteristics when installing arched conversion layer at different heights to the frame structure．
Research conclusions: Compared with the structure of no conversion layer，the intemal force of the structure member above the conversion layer changes a little while the internal force of the every flayer below the conversion layer increase much．For the structures of conversion layers at different heights。the internal force of the structure member below the conversion layer changes a litde while the internal force of the structure member above the conversion layer increase much．Under horizontal load，the deformation curve on the structure above conversion layer is shearing deformation mainly and the the deformation curve on the structure below the conversion layer is bending deformation mainly．The Conversion layer is the turning point between above and below deformation Curves．With no conversion layer，the max．Value appears on the low part of the structure．The top displacement increases with raising height of the conversion layer．The conversion layer is the place with small displacement between layers．Therefore，if the design is reasonable，the arched conversion layer Can have a perfect seismic performance．
