During the earthquake motion, limitation of storey drifts of is important. Maximum storey driftsfor the structures to be constructed in our country has been restricted by Turkish EarthquakeCode (TEC) which is in force since 2007, according to the provision of relative storey drift andA1, A2 irregularity factors. In the earthquake code which is published as draft in 2016 and is notin force yet, it has been planning to restrict the storey drifts for with and without gap conditionsof infill wall - frame connections. First of all, it is aimed to investigate the limits of maximumreduced relative storey drift under specified conditions according to TEC 2007. In this study, themaximum values of allowable reduced storey drifts were specified separately for reinforcedconcrete buildings which have 2.75m – 4.25m storey height interval, according to limitationsspecified in section of TEC 2007 that is “Calculation and Limitation of Effective Relative StoreyDrifts” for each of the Structural System Behavior Factors (R). Additionally, as an example,maximum relative story drifts have calculated according to “A1- Torsional Irregularity” sectionof TEC 2007 by using the relative storey drifts which belongs to a building from literature, andfor this building, maximum relative storey drifts has calculated according to “B2- InterstoreyStiffness Irregularity” section of TEC 2007 for variable interstorey heights. At the end of thestudy, maximum values of relative storey drifts in the floor have revealed according to averagestorey drifts and storey height ratios.
