Table 2 Limitations regarding column properties for the application of the simplified method of the EC4 design code
From: Practical ANN prediction models for the axial capacity of square CFST columns
Design code | Limitation |
|---|---|
Eurocode 4 (EC4) | \({\text{B}}/\text{t} \le 52\cdot\sqrt{{235/}{\text{f}}_{\text{y}}}\) |
\(235 \le{\text{f}}_{\text{y}} \le 460\, \text{MPa}\) | |
\(20 \le {\text{f}}_{\text{c}}^{ ^{\prime}} \le 50 \,\text{MPa}\) | |
\(0.2 \le \updelta \le 0.9\) |
