ABSTRACT
Reinforced concrete has been used for various construction works over the years. Numerous materials
and forms have been developed to come up with better concrete that can withstand bigger loads in
both tension and compression. One such material is the steel fiber. The steel fiber arranged randomly
has been proven be superior to the traditional reinforced concrete. This report aims at reviewing the
mechanical bending behaviour of Steel Fiber Reinforced concrete experimentally and using modal
assessment.
