Yield curvature (y) has been expressed in The paper presents closed-form equations for yield and ultimate moments and curvatures in rectangular reinforced concrete (RC) sections, with longitudinal reinforcement on all four sides 2012-06-01 · As a sensitivity check, we computed the following empirical proxies for each of the yield curve latent factors: (9) Level = y t (120), (10) Slope = [(y t (3))-(y t (120))], (11) Curvature = [2 × (y t (48))-(y t (3))-(y t (120))], where (y t (m)) refers to the zero-coupon bond yield of maturity m (in months). 7 Their correlations with the model estimates are 97%, 93% and 75%, respectively for the level, slope and curvature, which are in line with the correlations presented in k = y ″ ( 1 + y ′ 2 ) 3 2 , {\displaystyle k= {\frac {y''} {\left (1+ {y'}^ {2}\right)^ {\frac {3} {2}}}},} for the signed curvature. In the general case of a curve, the sign of the signed curvature is somehow arbitrary, as depending on an orientation of the curve.

Moreover, axial load ratio which may affect the yield curvature has not been parameterized and no limitation has been introduced for the application of the formula. However, bridge columns designed according to most design codes may have the axial load ratio (P/f’ c. A. g; where .

But there are also corporate issuer’s yield curves, credit rating based yield curves, LIBOR curves , OIS curve, swap curves (which are a type of yield curve), and several other types of curves that haven’t been touched upon. yield curvature to the ratio of the longitudinal reinforcement.
