Figure A2-2. Example of interaction curves. fck = 40, co = 0,2, çef =2. general method

- stiffness method, expressions (5.22)-(5.24)

curvature method, expressions (5.31)-(5,36) (upper curve, Ky = 1)

--------- curvature method, expressions (5.31)-(5.37) (lower curve, according to (5.43))*

^ For Ä = 105 and 140, (5.43) gi\>es K0 = 1, therefore there is only one curve in these cases.
