In the past earthquakes, the field surveys performed on the single-story precast RC industrial buildings reveal that the main reason for severe damages in those structures were due to the insufficient lateral stiffness. These high period structures exhibit more flexible behavior than conventional reinforced concrete structures. In this study, different code status single story precast RC industrial building models have been considered. Limit drift values for four different damage states such as slight, moderate, extensive, and complete have been investigated based on Park and Ang damage index values. These damage index values are obtained from incremental dynamic analysis. Incremental dynamic analysis is conducted for 25 earthquake ground motion records. The results of current study show that there is an increase in mean drift values obtained for each damage case taken from low code to high code. In the final step, values of current study are also examined in comparison with the values recommended for low-rise prefabricated building class in HAZUS. It is believed that the limit drift values presented in the study will allow a practical and rapid evaluation of the vulnerability of the considered structure.
