Abstract:

Article Preview

To understand mechanical characteristics and seismic behaviors of T-shaped concrete-filled steel tubular (CFST) joints, cyclic loading tests were carried out on four 1/2-scale exterior joints of top floor. The study includes joints’ mechanical character, failure mode, hysteretic behavior, ductility, energy dissipation and stiffness degradation under different height of beam and different axial compression ratios. The results indicate that frame joints satisfy the design principle of stronger joints and weaker components. The hysteretic loops are plump, ductility and energy dissipation capacity is better than that of ordinary reinforced concrete joints. Axial compression ratios can influence seismic behaviors of frame joints to some degree.
