Özet

This paper presents the analytical results of six steel bolted T-connection models and four steel bolted beam-to-column connection models with top and seat angles. This study was undertaken to analyse the influence of bolted T-connections instead of welded connections and the influence of angles with and without stiffeners on the behaviour of the beam-to-column connections under hysteretic loading. The aim was to compare the energy dissipation of different connections with each other. The energy dissipation characteristics are obtained from the main characteristics of moment-rotation hysteresis curves. This study shows that the energy dissipation decreased by about 2-29 % and 2-13 % for bolted T-connection and top-and-seat-angle connection models respectively after switching from one cycle to another in five hysteretic loadings.
