Performance Of UPHC Filled Steel Column

Ever since the development of the Ultra-High-Performance Concrete [UHPC], research has been going on in the use of hollow steel tubes filled with UHPC as a super-frame structural member. The key area of this research is to study the influence of confinement effect on the behavior of the Super-frame column and to develop guidelines in modern codes for the design of such composite sections. This project report compares the performance UHPC filled steel tubes and conventional sections using a computer program, Lab experiment and analytical analysis. The results of all the analysis show that UHPC filled tubes perform better than the conventional sections such as only steel sections or concrete sections. Additionally, Eurocode - 4 predicts reasonable results.
