Cement Composites: Analysis and Design

There are numerous advantages of using the a fiber reinforced concrete system in applications such as elevated slabs, industrial floors, and structural thin sections.  The key advantage is in the time reduction of the installation as the double layers of traditional rebars and stirrups which can result in several weeks of construction time.

Structural design procedures have been proposed based on material properties obtained from full-scale tests, large scale round panel tests, and flexural beams to verify the design calculations.  A combination of small scale flexural beams, round panel tests, finite element modeling, and full scale testing of suspended slabs leads to better understanding of the mechanisms involved.
