Crack resistance capacity of SRUHSC column to RC beam joint under frequent earthquake load

摘要

In order to investigate the crack resistance capacity of steel reinforced ultra high strength concrete (SRUHSC) column to reinforced concrete (RC) beam joint under frequent earthquake load, six interior joint specimens were tested with various axial load ratio and volumetric stirrup ratio. A discussion on the crack resistance capacity was presented. Calculation method of crack resistance capacity was deduced and calculating results were in good agreement with the experimental results. The research results indicated that parameters of SRUHSC column to RC beam joint with better crack resistance performance may be referred for engineering application.
