The results of tests conducted on four Engineering Wood Encased Concrete-Steel (EWECS) composite columns using single H-steel are presented. The columns were tested under constant axial load and lateral load reversals. The main test variable was the type of column-stub connection. The results indicated that EWECS columns had excellent hysteretic behavior without severe damage, even at large story drift of 0.04 radian. Moreover, the type of column-stub connection consisting of woody shell and wood panel attached to stub showed high performance in both capacity and damage limit of the columns. |
