![]() In this study, a simplified beam-to-column connection is presented which was specified in EC3 Annex J. The effect, at the global a nalysis stage, of having semi-rigid joints instead of rigid or pinned jo ints will be to modify not only the displacements but also the distribution of the internal forces in the structure. ![]() The mome nt and relative rotation are related through a constitutive law which depends on the joint properties. In a frame with semi-rigid joints the loading will create both a bending moment a nd a relative rotation between th e connected members. Recent limit state specifications permit the concept of semi-rigid connection of the individual frame members in the structural design. ![]() Conventionally, the anal ysis of frame structures is based on the assumption that all connections are either frictionless pinned or fully rigid. The frame el ements are constructed from a predetermined rang e of section profiles. In this paper, a genetic algorithm is pr oposed for discrete minimal we ight design of steel planar frames with semi-rigid beam-t o- column connections. ![]()
