In steel or composite gable frame construction, steel element with tapered H-seition is often used. The web with high height-thickness ratio is usually applied for tapered H-section members, where local buckling may occur. Seven steel columns with tapered H-section under cyclic loading are examined, in which the local buckling of web plate, hysteretic curves, energy dissipation. and failure mode are focused on. Various factors affecting load-carrying capacity and energy dissipation are evaluated. From experimental studies, it is found that the steel members with tapered H-section and high width-thickness ratio web may be less ductile; the hysteretic behavior may be affected by the initial imperfection of the web and the axial force. Some valuable suggestions on using this kind of column for structures in seismic zone were presented. [ABSTRACT FROM AUTHOR] |
