On the other hand, depending on the application in question, the predictions of ACI are sometimes unconservative and sometimes conservative.

Concrete cone failure – Wikipedia

BoxRedford Station, Detroit In the case of concrete tensile failure with increasing member size, the 39-85 load increases less than the available failure surface; that means the nominal stress at failure peak load divided by failure area decreases.

The model is based on fracture mechanics theory and takes into account the size effectparticularly for the factor h e f 1. Based on this, the CCD method is recommended as the basis for the design of fastenings. For large head size, the bearing pressure in the bearing zone diminishes.
