Appraisal of Partially Restrained Steel Columns in Nonsway Frames

摘要: This paper describes an analytical study to investigate the behavior of subassemblages with a range semirigid connections under different test conditions and loading arrangements. The αpin concept, which gives indication benefit restraint from beam-to-column connection after incorporating potentially disadvantageous influence moment through connection, is validated. It noted that M-ϕ response fundamental importance success or failure design methods rests on it. However, it most difficult parameter determine accurately. results in this have shown significant variations negligible effect load carrying column subassemblage. implies precise form not important for capacity braced frames. Due boundary condition model, these only translate into frame behavior.
