In t he new specificati ns, c ntent f design and c nstructi n n synthetic fiber reinf rced c ncrete is added, the r und straight steel fiber f l w strength and t he melt extracted steel fiber w it h l w er c ntaining f carb n are eliminated, high strength fiber cut fr m steel w ire, specially shaped fiber milled fr m steel ing t r sheared fr m steel sheet and melt extracted steel fiber w ith l w all y are rec mmended. The strengt h grade f fiber reinf rced c ncrete is extended fr m 40MPa t 80MPa. T take int acc unt t he effects f steel fibers n different strength c ncrete, different effect ing fact rs are given t estimate perf rmances f the c ncrete w ith dif- ferent strengt h grade and each c mputati n f elements made f the fiber reinf rced c ncrete. The t ughness f fiber reinf rced c ncrete is induced int the design f tunnel liner and industrial fl r. The design and c nstructi n meth ds f r f slab, pile cap, c rbel, deep beam, pavement f d ck and bridge, bridge structures, structures f hydraulic en- gineering, layered c mp sit e pavement, and s n, are added.
