Steel moment frame system is one of the conventional and practical systems in bearing lateral loads that is used individually or in combination with other systems in seismic areas and tall structures. The joints are The most important members of a moment frame system and The function of the connection varies according to the ductility of the moment frames. Therefore, research on the performance of these connections in steel structures is of particular importance, because low accuracy in its design and execution, in addition to the failure of the connection, will cause high damage to the entire structure. Today, the American Institute of Steel Construction (AISC) and the Iranian National Building Code introduce patterns as pre-qualified acquisitions. Over the course of three decades, several studies have been conducted several times on steel flexural joints with side stiffeners. On the other hand, considering that fragility curves are a suitable tool for diagnosing vulnerability. This article tries to examine the adequacy of the steel moment frame using side stiffener connection and pre-qualified WUF-W connection and providing a fragility curve then comparing them with each other. The result shows that the structure is less likely to fail using a steel moment connection with side stiffener instead of pre-approved WUF-W connection.
