Dynamic response prediction of steel frame structure considering semi rigid connection

The actual behavior of beam to column connections in steel frames is seldom fully rigid or fully pinned. The actual behavior of the connections is usually semi-rigid. Neglecting the real behavior of the connection in the analysis may lead to unrealistic predictions of the response and reliability of...

description The actual behavior of beam to column connections in steel frames is seldom fully rigid or fully pinned. The actual behavior of the connections is usually semi-rigid.
