Abstract :
By increasing information on buildings behavior in the earthquake and codes updating, concerns exist about the seismic state of a large volume of existing buildings built without the application of new criteria. To verify this, we need to carefully evaluate the members of the buildings constructed with various editions of the 2800 code and identify vulnerable members of buildings designed with different editions of the code, and have a comparison between the various editions of the 2800 code. Given that the 2800 code is applicable to the design of new buildings and cannot be used to evaluate buildings constructed in accordance with previous codes, then we need to use a seismic rehabilitation instruction to evaluate buildings based on specific performance and certain hazard levels. The purpose of this paper is to identify vulnerable members of buildings designed with various editions of the 2800 code. In order to achieve this goal, we first design 2 buildings of 5 and 6 floors by the first, second, third, and fourth editions of the 2800 Code. In the following, after analyzing and designing with the different editions of the 2800 code, a comparison with the fourth edition of this code and the assessment of the members of the buildings based on the criteria for "Instruction of seismic rehabilitation of the existing buildings" (360 Publication) is made.
