Abstract
Current trend in the estimation of seismic demand for reinforced concrete structure has been widely been based on forced based analysis. Adaptive Pushover method is advancement in the convention methods. Forced based scaling in adaptive pushover (FAP) analysis involves forced based controlling parameters. The force vector for pushover is incremented with every step of analysis, rather than Modal Pushover analysis which has the force vector based on the modal shapes until 90% modal participation factor is attained. Displacement based adaptive pushover analysis shows relatively appealing concept. In the present paper 8 storey MR frame is studied and comparison is done among force based adaptive pushover, displacement based adaptive pushover and non-linear time history analysis considering NTH analysis to be exact.
