Incremental dynamic analysis（IDA）is the most realistic and advanced analysis method with sufficient earthquake inputs.Static pushover analysis is more simple and practical

and it can better describe the process that from elastic deformation to yield until collapse.The seismic performance of RC core walls is evaluated through the IDA and Pushover methods.The results show that the outputs from IDA method for the required levels of performance（including normal service

temporary service

life safety and collapse prevention）have limited errors

as compared with Pushover method.But it is still within the usual margins of error.The top displacement angle limit value is too large by IDA method.Pushover analysis results are different from the elastic-plastic seismic response results of the actual structure because that Pushover analysis under single lateral force cannot consider the impact of higher modes and ground motion factors.
