表2 3种传统经验公式

Table 2 Three traditional empirical formulas

Traditional empirical formulas	Calculation formula
Model one^[5]	$β = \frac{1}{d} (32.43 + 0.303 f_{c u} + 0.65 c + 27.45 w)$
Model two^[27]	$β = 94.82 \times 1 . 018^{c} f_{c u}^{0.248} d^{- 1.588}$
Model three^[38]	$w = 4.5045 δ + 0.04955, β = [1 - {(1 - \frac{2 δ}{d})}^{2}] \times 100 %$
