Materials, Coefficients, Notation
The following notation for material parameters is used:
Rbd | - | design compressive strength of concrete |
Rbtd | - | design tensile strength of concrete |
γu | - | coefficient of the shape of cross-section |
z | - | lever arm (arm of internal forces) |
Coefficient γu is given by equation (Art. 5.2.2):
The most common notation for geometrical parameters:
b | - | cross-section width |
h | - | cross-section depth |
he | - | effective depth of the cross-section |
z | - | lever arm (arm of internal forces) |
