The main objective of this study is interpreting the probable dependency of structural performance level and itscorresponding inter-story drift in conventional RC moment frames. For this purpose, inter-story drift as dependentvariable and other structural characteristics such as strength of materials, structural dimensions and internal loads asindependent variables have been assumed. Specimens were studied by means of pushover analysis, then independent anddependent variables have been recorded for each member. Correlation of all variables were examined extensively andfinally accurate equations have been proposed to predict inter-story drift at performance objectives.
