Fiber-Reinforced Concrete For Hardened Shelter Construction
Abstract
A test program was conducted to develop a fiber- and rebar-reinforced beam design(s) using lightweight, high-strength concrete. The goal of the testing program was to develop a beam design(s) that provides superior performance at a reduced cost and weight versus the symmetrically rebar reinforced beam design using normal-weight, standard-strength concrete currently used by the U.S. Air Force in hardened structure construction. Beams of various designs, including a baseline symmetrically reinforced beam designed using current hardened structure criteria, were fabricated and tested on a load-frame under deflection control and flexural third-point loading to generate load- deflection curves. From these curves, the ductility, energy absorption characteristics, and overall material toughness of each beam design were determined.
