A large number of engineered as well as non-engineered buildings were severely damaged and collapsed during a magnitude 7.1 earthquake in Iran. This paper reports the damage on RJC frame structures and describes their possible causes. It is revealed that most of the R/C framed structures suffered damages due to the lack of seismic resistance design practices and poor reinforcement detailing. Results of nonlinear earthquake response analysis of a typical damaged building showed that the degree of damages could greatly decrease with a proper earthquake resistance design and reinforcement detailing.
