Crack Pattern and Ductility of Connections Composed of CSSEUHSC Columns and SEC Beams under Cycle Loads
In order to investigate the crack pattern and ductility of connection composed of cross shaped steel encased ultra high strength concrete (CSSEUHSC) columns and steel encased concrete (SEC) beams under cycle loads, six interior connection specimens were tested in the laboratory. It was found that cracks appeared in the connection core regions and at the beam end for all specimens, and all the connections behaved in a ductile manner and failed in bending with a beam plastic hinge and shearing in the connection core region. The experimental results indicated that test parameters of connection composed of CSSEUHSC columns and SEC beams with good crack resistance performance may be referred for engineering application.
