PREDICTION OF SPACING AND WIDTH OF CRACKS FOR STEEL FIBRE REINFORCED SELF COMPACTING CONCRETE FLEXURAL ELEMENTS

摘要：

An attempt is made to predict spacing and width of cracks for steel fibre reinforced self compacting concrete flexurai elements. The aspect ratio (15, 25 and 35) and volume fraction of steel fibres (0, 0.25, 0.5 and 0.75％) were varied to obtain the loads corresponding to known crack widths ranging from 0.3 to 0.1 mm so as to obtain 45 test results. These test results were compared with the proposed model which is a modification of Desayi and Ganesan (1985) and the comparison was found to be satisfactory with respect to the accepted literature.
