［摘要］我國現(xiàn)行的鋼纖維混凝土結(jié)構(gòu)設(shè)計依據(jù)主要為《纖維混凝土結(jié)構(gòu)技術(shù)規(guī)程》（CECS 38∶2004），該規(guī)程采用的是影響系數(shù)法，而我國現(xiàn)行《混凝土結(jié)構(gòu)設(shè)計規(guī)范》（GB 50010—2010）采用的是力學(xué)指標(biāo)法。闡述了以上兩種方法的不同之處，指出了目前我國鋼纖維混凝土設(shè)計采用影響系數(shù)法的不足，并提出了回歸力學(xué)指標(biāo)法的建議。

Abstract:Chinese current steel fiber reinforced concrete structural design method is mainly based on the Technical specification for fiber reinforced concrete structures (CECS 38∶2004), and  this specification adopes the influence coefficient method. But  Code for design of concrete structures (GB 50010—2010) adopts the mechanical index method. The differences of the two methods were compared, and the shortcomings of the influence coefficient method for steel fiber reinforced concrete design  were discussed, and it is suggested to adopt mechanical index method.

Keywords:steel fiber reinforced concrete; influence coefficient method; mechanical index method
