Abstract: Based on a triangular frameRC core wall structure, the selection, arrangement and seismic design of structure were discussed starting from the seismic conceptual design. The seismic performance of the structure was evaluated under frequent earthquakes and rare earthquakes. The critical element of the structure was calculated under earthquake resistance. The analytical results showed that the structure had well seismic performance; the arrangement of structure was reasonable and the seismic tectonic measures were put forward on this basis.
