Abstract

Given the performance-based approach to earthquake engineering, and the importance and necessity of proper and fundamental management of potential crises such as earthquakes, the need for tools for realistic assessment and understanding of structural and non-structural systems as well as proper damage assessment. Possible, followed by logical decisions, are becoming more and more important. Structural assurance has always been a principle for engineers responsible for designing construction projects. One of the mechanisms that has received increasing attention in recent decades is called progressive failure, which, due to accident or attack, destroys one or more members of a sudden structure and then the building progressively breaks down. What will be discussed in this article is a close examination of this type of damage to steel structures that has so far not been addressed in Iran. In this regard, we will examine these types of structures that are widely used in metropolises such as Tehran today. What is expected from the dissertation is the behavior of the two failure modes progressively occurring in the desired structure so that the results of the dissipation curves obtained in this thesis are in three stages (healthy and two modes). In removing some beams and columns) are compared with each other. Therefore, the failure state of the structure will be considered as a variable in this structure. In this project three modes are considered and the results are compared with each other. The results can be used to design structures in non-operational defense mode.
