ABSTRACT

A summary is presented of a number of representative studies on the use of HPFRCC in combination with conventional reinforced concrete and prestressed concrete. Examples of applications with reinforced concrete include the effect of fiber reinforcement on plastic rotation and ductility index; the use of fibers in the tensile zone area of reinforced concrete beams to control cracking and improve durability; the use of a SIMCON layer as reinforcement in a composite slab system; the use of SIMCON for repair and rehabilitation of reinforced concrete beams and columns; the use of fibers to improve shear resistance and replace shear reinforcement; the use of fibers to improve the seismic performance of reinforced concrete monolithic or cast-in-place framing joints subjected to cyclic loading; and the use of fibers to improve the impact resistance of reinforced concrete beams. Examples of applications with prestressed concrete include the reduction of transfer length of pretensioned strands due to fiber reinforcement, and the improved ductility of beams prestressed with fiber reinforced plastics reinforcements. A brief section on structural modeling is also provided.
