COLLAPSE OF INFILLED STEEL FRAMES WITH SEMIRIGID CONNECTIONS

The response of panels, consisting of semi-rigidly connected steel bea ms and columns with infilled shear panels, to lateral forces was evalu ated using limit analysis: Thereafter a study was made of design metho ds, in order to incorporate such concepts in design examples. As a wid e variety of connection types are used in practice, it is impractical to utilize the precise properties of individual connections. Therefore , a scheme is developed whereby connections are classified in terms of their strength and stiffness using moment-rotation data. The results from an investigation into the influence of these joints on the behavi our of structural panels are presented.
