• Size effect in self consolidating concrete beams with and without notches

The aim of this study is to obtain the fracture characteristics of low and medium compressive strength self consolidating concrete (SCC) for notched and un-notched plain concrete beams by using work of fracture $G_F$ and size effect model $G_f$ methods and comparing them with those of normal concrete and high performance concrete. The results show that;

with an increase in compressive strength, $G_F$ increases and $G_f$ decreases;

with an increase in depth of beam, the decrease in nominal stress of notched beam is more when compared with that of a notchless beam.
