000011599 520__ $$2eng$$aThe construction of a wide range of typical Iranian steel buildings a large number of which were built before 1990 was based on no seismic code. According to the experiences of past earthquakes, especially Manjil Earthquake (1990) and Bam Earthquake (2003), it has been confirmed that many of these steel buildings may suffer extensive damage while earthquakes. Considering that some of these buildings are critical facilities that must remain operational following earthquakes, serious concerns are raised about their performance in future earthquakes. Observation of damaged Iranian steel buildings shows that most of them have failed due to their joint failure. The beam-to-column connections of these buildings follow the practice of Iranian typical connection named as “Khorjini connection”. In this study, following the evaluation of existing Khorjini connections, a connection upgrading method which significantly improves the seismic performance of these connections is proposed. In order to demonstrate the effectiveness of the proposed method, three Iranian common steel buildings that can be representative of low-, medium-, and high-rise buildings have been analyzed by linear static, nonlinear static (pushover), and nonlinear dynamic (time history) methods. Results obtained from these analyses also approve the success of suggested method in upgrading the seismic behavior of Iranian common steel buildings.
