摘要：
The present paper describes experimental tests performed on 12 compound square columns. The columns had an inner core made of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC), class C150 and a steel reinforced outer layer (shell) which was cast using C50/60 class concrete. The object of the research program was to determine the efficiency of this type of elements when subjected to centric compression and the possibility of reducing the cross section of columns in structures. The experimental program described in this paper shows that using UHPFRC cores is an effective means of reducing columns' cross sections.
