Method of analysis for second order effects, based on nominal curvature: the nominal second order moment M2
Eurocode 2 part 1-1: Design of concrete structures 5.8.8.2 (3)
The nominal second order moment M2 is defined by:
| M2 = NEd e2 | (5.33) |
where:
- NEd
- is the design value of axial force
- e2
- is the deflection, e2 = (1/r) l02 / c
with
- 1/r
- the curvature.
- l0
- the effective length, cf. 5.8.3.2
- c
- a factor depending on the curvature distribution.
For constant cross section, c = 10 is normally used. If the first order moment is constant, a lower value should be considered (8 is a lower limit, corresponding to constant total moment).
This application calculates the nominal second order moment M2 from your inputs.
