Abstract

Self-compacting or self-placed concrete is a high-performance concrete that is characterized by the fact that it can be placed through dense reinforcing steel, and give compact concrete and highly flat surfaces under only the influence of its own weight, without the use of other tools. Since this product is young, studies on it are many and varied, especially its behavior in resisting shear stresses due to collapse. Because of this, the concrete is usually fragile and abrupt.

Shear calculation Equations for ordinary concrete in many international codes ignore the size effect factor (a/d) on this resistance, and to date there is no approved equation in these codes to predict the resistance of self-placed concrete to shear stresses, and therefore in this research we have done A statistical study on the development of the Frosch2003 equation [5] to calculate the shear strength of ordinary concrete, which the research [4] recommended could be developed to predict the shear strength of beams of self-compacted concrete, as the equation developed to calculate the shear strength of self-placed concrete gave values ​​consistent with the results of reference studies. Its performance factor correlation coefficient was R = 0.92 and the deviation coefficient COV = 17.5%, and therefore it can be adopted in calculations.
