TEST ON 2-BAY 2-STORY CES FRAME SUBJECTED TO LATERAL LOAD REVERSALS
This paper summarizes the results of static loading test carried out on a two-bay two-story concrete encased steel (CES) frame. The structural members of the CES frame consist of only encased steel and fiber reinforcement concrete (FRC). The specimen was about a half-scale model, which simulated the lower 2.5 stories and 2 spans of the middle frame in 15-story CES frame buildings. It is predicted that the beam flexural failure near the interior beam-column joint occurred on the CES frame followed by the failure on all the bottom of columns. However, the failure on the joint panel of the interior beam-column joints also occurred at R of 0.01 rad. The specimen reached the maximum ultimate shear force at R of 0.02 rad. The results also showed that the use of FRC in the CES frame reduced the damage of the concrete in the frame. In addition, the hysteresis loops showed a stable behavior with almost no degradation of load carrying capacity until maximum story drift angle, R of 0.05 rad., indicating that the CES frame has excellent seismic behavior.
