This paper analyzed the reasons of early age cracking of reinforced concrete floor, and proposed the calculation model of early age cracking of reinforced concrete floor. Solution process of early age cracking of reinforced concrete floor was described in detail through a calculation example. Comparison between the method provided in this paper and the finite element analysis method was conducted. Measures were discussed when the early cracking appeared. The further research contents needed were indicated in this paper.
