| Abstract: | The effect of steel fiber volume ratio on the cracking,resistance moments of a corbel normal section was taken into consideration according to the results tested. Application of the normal section's cracking,resistance moment calculation of a beam to the same calculation for the corbel has led to a formula for calculating the normal section cracking,resistance moments of a steel fiber reinforced concrete corbel. The results calculated from this method well conform to those of testing. Its profits are easy calculation,practical use,having the same calculation conception as the general reinforced concrete corbel. The method would be possible to be applied for similar construction designs. |
