Abstract:
The seismic responses of a 6-story reinforced concrete(RC)frame with and without the rocking-wall were compared using the elastic-plastic time history analysis by general finite element software SAP2000. The analysis results show that this system is forced to vibrate on a rocking mode during the earthquake. The failure mechanism of this structure is overall yielding mechanism instead of story yielding mechanism when it gets damaged. The overall yielding mechanism endows satisfactory energy dissipation capacity of the structure. The story drift becomes more uniform distributed and the deformation concentration phenomena significant improved thanks to the rocking-wall. The first story drift can also be effectively controlled even if the additional height of rocking-wall only reaches half of the entire height of structure. The RC frame rocking-wall structure system has satisfactory seismic performances.
