چکیده مقاله :
In this study, the pre-approved connection and the proposed connection have been investigated and analyzed using Abaqus finite element software. Non-linear static analysis was performed with reciprocating loading. In this study, in order to compare the proposed connection and the direct connection, two one-story and six-story frames has been modeled and the behavior of the two connections in these frames has been investigated. According to the software models, it can be seen that in all the models, the bending moment capacity of the connection is more than 40% of the calculated plastic moment in the connection. In connection with the reduced cross-section, this percentage has reached nearly 20%. The results of the proposed connection behavior show that it performs nearly 25-34% better than the pre-validated connection of the 10th topic of Iran regulation of structures. The structure with the proposed connection has a higher coefficient of behavior than direct connection. With the increase in the height of the structure, the coefficient of behavior of the structure has also decreased.
