Composite C-C Columns by Utilizing of UHPFRC

Abstract:

Main advantage of composite concrete columns, in comparison with traditional reinforced concrete columns, is its increased load-bearing capacity by using of solid steel reinforcing core. Ordinary type of such a steel-concrete (S-C) composite column consists of normal concrete and different type of solid steel core. In last decades high quality concrete is more and more used for load-bearing structural members exposed compression like columns. Present knowledge level in the area of ultra-high quality of concrete open a new chance for utilization of this progressive structural material in concrete building industry. This paper presents some new information and laboratory test results of concrete-concrete (C-C) composite columns by utilizing of UHPFRC.
