FRAMES WITH SEMIRIGID STRUCTURAL CONNECTIONS

Abstract

During recent years, researchers have focused their attention on the actual behaviour of beam-to-column joints. In general, structural analysis of frames are performed either for rigid joints or pin-ended connections. Nevertheless in practice, no joints are either fully rigid or actually pinned. A presumed rigid joint always allows for a relative rotation or presumed pin-ended connections are never proper hinges. Therefore all joints should be treated as semi-rigid. To meet semi-rigidly connected behaviour an empirical interaction equation, given in Turkish Standard TS 4561, is adopted into analysis by using Cm values which modifies the moment relating with effective buckling length of member, where Cm values are different for rigidly and semi rigidly connected frame elements
