Is the exponent n applied differently from the design standard when determining the distribution coefficient ζ (zeta)?


Yes, the exponent n is applied differently. This can be better understood in the calculation details. For EN 1992-1-1, for example, n=2 is applied (see Figure 01) and for CSA A23.3-14, n=3 (see Figure 02) is applied.
