RC frame rocking wall structure is a new structure system, which combines RC frame with rocking wall. A 6-story RC frame following current design practice is taken as an example to study the seismic behavior of the new system. Elastic-plastic model is established, and pushover analysis is conducted by using a finite element program called Abaqus and a user subroutine library called PQFiber. The analysis results suggest that: (1) the rocking wall can significantly improve the strength and ductility of the entire structure. (2) Thanks to the rocking wall, the inter-story drift becomes more uniformly distributed and the story failure mechanism is prevented, although the rocking wall does not contribute much to avoid the ‘Strong beam weak column’ yielding mechanism. (3) The inner force distribution of the rocking wall is similar to a veridical placed simple supported beam.
