Small End Restraint Effects on Strength of H-columns

摘要: A parametric study of the strength and behaviour an axially loaded wide-flange steel column is investigated from viewpoint a beam analysis using approximate deflection method bi-linear fitting for test data moment rotation relationships beam-to-column connections taking into consideration effects residual stresses, geometric imperfections small end restraints. computer program developed to obtain numerical results, which effective length decreasing factor maximum load increasing are proposed. The validity model demonstrated by comparison with results on actual column.
