The theory of linear fracture mechanics, which depend dependent of structure size (no size effect), is represented by the straight discontinuous size of a structure, is represented by the inclined discontinuous asymptote with a asymptote (strength criteria). The theory of linear fracture mechanics, which is determined by -1/2. Nonlinear fracture mechanics theory, discontinuous asymptote using a slope the tw the size of a structure, is represented by the inclined which can be intermediate among of – theories, is illustrated by the continuous curve in the figure [2]. This curve is ous 1/2. Nonlinear fracture mechanics theory, which is intermediate among the two previous theories, is illustrated the structure size is small and approaches the -1/2 the horizontal line, whereby the continuous curve within the figure [2]. This curve is close slop towards the horizontal line, where the structure size is little and approaches the -1/2 slope as size increases. the size increases.Figure 1. Shear strength with rising size.

Table 1 shows decreasing terms from some shear resistance prediction models for conventional RC beams ([25,325]). All these Table 1.

In the following, examples of size impact consideration by some codes for the design 877 of traditional RC structures are presented. Note that the size impact influences only the concrete contribution to shear resistance. As a result, the size effect correction (reduction) element is applied directly to the concrete contribution.
