Four editions of the Iranian Code of Practice for Seismic Resistant Design of Buildings have been published. Obvious changes have been made between the second and third editions regarding the seismic design of reinforced concrete buildings. This research focuses on evaluating the design reliability and seismic performance factors provided in the Standard No. 2800-99 (second edition) and Standard No. 2800-05 (third edition). The performance and seismic characteristics of the seismic design codes were evaluated by using the FEMA P695 methodology. A set of 48 reinforced concrete structural systems and 2112 incremental dynamic analyses were conducted, according to the FEMA P695 methodology. Etabs software was used for preliminary design of the structures, and SeismoStruct software was applied for the sake of nonlinear analyses. The results reveal the vulnerability of certain building stocks designed based on the second edition. Furthermore, the life safety performance level, which is an essential factor according to Standard No. 2800-99, is challenged. In contrast, the structural systems designed based on the Standard No. 2800-05 fulfill the requirements for moderately intense earthquakes.

已出版了《伊朗建筑抗震设计操作规范》的四个版本。在第二版和第三版之间，关于钢筋混凝土建筑的抗震设计已发生了明显的变化。这项研究的重点是评估标准2800-99（第二版）和标准2800-05（第三版）中提供的设计可靠性和抗震性能。使用FEMA P695方法评估了抗震设计规范的性能和抗震特性。根据FEMA P695方法，进行了一组48个钢筋混凝土结构系统和2112个增量动力分析。Etabs软件用于结构的初步设计，而SeismoStruct软件则用于非线性分析。结果揭示了基于第二版设计的某些建筑材料的脆弱性。此外，作为标准2800-99的重要因素，生命安全性能水平受到了挑战。相反，基于标准2800-05设计的结构系统可以满足中等强烈地震的要求。
