The following notation for material parameters is used:
Rb | - | design compressive strength of concrete |
Rbt | - | design tensile strength of concrete |
Rsc | - | design compressive strength of steel |
Rs | - | design tensile strength of steel bar |
The most common notation for geometrical parameters:
b | - | cross section width |
h | - | cross section depth |
h0 | - | effective depth of cross section |
z | - | lever arm (arm of internal forces) |
