Since they offer many alternatives for shopping, eating, resting, etc. many people spend a considerable time in shopping mall buildings. Therefore, this type of building is increasing rapidly. The increment rate was almost three in Turkey for the last decade. The recently released seismic code of the country has some serious alterations such as increased seismicity of some regions and reduced performance level limits of structural members. Besides, the building importance factor (I) of the shopping malls was defined clearly to be 1.2 whereas some shopping malls were designed considering I = 1.0 and constructed before 2018. Therefore, seismic performances of the shopping malls became questionable according to the code. In this study, seismic performances of two existing shopping mall buildings, which were designed and constructed by considering I = 1.0, are investigated based on the recently released seismic code and nonlinear analyses in which the utilized records were scaled considering I = 1.2. The results showed that the increased seismicity and reduced performance level limits may lead to excessive story drifts and plastic rotations for some records. However, the mean value of the analysis results satisfies the life safety (LS) performance level. Therefore, the importance factor might be suggested to be 1.0 for shopping malls close to the faults to avoid an unnecessary increment of the initial cost.

由于它们为购物、饮食、休息等提供了多种选择，因此许多人在购物中心建筑中花费了大量时间。因此，这种类型的建筑正在迅速增加。在过去十年中，土耳其的增长率几乎为 3。最近发布的国家抗震规范有一些严重的变化，如部分地区的地震活动增加，结构构件的性能水平限制降低。此外，购物中心的建筑重要性因子（I）明确定义为1.2，而一些购物中心的设计考虑了I = 1.0并且在2018年之前建成。因此，根据规范，商场的抗震性能受到质疑。在本研究中，根据最近发布的地震规范和非线性分析，研究了考虑I = 1.0设计和建造的两座现有购物中心建筑的抗震性能，其中使用的记录按I = 1.2进行缩放。结果表明，增加的地震活动性和降低的性能水平限制可能导致某些记录的过度位移和塑性旋转。然而，分析结果的平均值满足生命安全（LS）性能水平。因此，对于靠近故障点的商场，可以建议重要性系数为1.0，以避免不必要的初始成本增加。
