STRUCTURAL SYNTHETIC MACRO FIBERS

by David G. Flax

This presentation covers the many advantages of using structural synthetic macro fibers to replace rebar and welded wire fabric for slabs-on-grade, composite metal decks, toppings, and shotcrete. These advantages include freedom from corrosion and the fact that the reinforcement is always in the correct location - three dimensionally from top to bottom. Covers two programs that can be used to determine the correct dosage. One matches the dosage to the designed steel. The other was developed for structural slabs-on-grade and incorporates applied loadings such as vehicle loads, post & rack loads, line loads, point loads, forklift loads, and uniform loads along with many other factors. The program is based on ACI 360 “Design of Slabs on Ground”.
