Abstract
In order to investigate the crack pattern and ductility of connection composed of cross shaped steel encased ultra high strength concrete (CSSEUHSC) columns and reinforced concrete (RC) beams subjected to reversal cycle load, six interior connection specimens were tested with various axial load ratio and volumetric stirrup ratio. A discussion on the ductility and crack pattern was presented. It was found that cracks appeared in the connection core regions and at the beam end for all specimens, and that axial load ratio had more influence on the crack resistance capacity. The experimental results indicated that test parameters of connection composed of CSSEUHSC columns and RC Beams with good crack resistance performance may be referred for engineering application.
