Here the hsc of sompa is achieved through adding super - effective water reducer , fined slag and silicon fume , and decreasing the water / cement ratio . by varying the area ( spacing ) of tension bars , compressive bars , vertical links and distribution steel and embedding steel fiber and polypropylene fiber we try to improve the behaviors of reinforced high performance concrete one - way spanning slabs in bending , so that its ductility be greater than 5 . with the same arrangement of steel the width of bending member is varied to observe the effect of the width / depth ratio on the ultimate compressive strain of concrete
The research shows that : 1 ) the ductility of the hsc bending members constructed is much greater than 5 ; 2 ) increasing the vertical links and distribution steel can increase the deflection under ultimate moment ; 3 ) with appropriate compressive bars , vertical links and distribution steel the increase of moment after yield and the decrease of moment under ultimate moment can be ignored , so the ductility of the hsc bending member is much larger ; 3 ) the width / depth ratio of hsc bending member has no obvious effect on the ultimate compressive strain of concrete ; 4 ) the method used here to calculate the deflection is applicable ; 5 ) the location of crack coincides with the location of vertical links and distribution steel ; 6 ) the bending property of the hsc structure under the blast load can meet the demand of protective engineering
