# Geometric imperfections: the inclination `θ`_{i}

_{i}

## Eurocode 2 part 1-1: Design of concrete structures 5.2 (5)

Imperfections may be represented by an inclination, `θ _{i}`, given by:

θ = _{i}θ⋅_{0}α⋅_{h}α_{m} | (5.1) |

where:

`θ`_{0}- is the basic value, see § 5.2 (5)
`α`_{h}- is the reduction factor for length or height:
`α`= 2/√_{h}`l`; 2/3 ≤`α`≤ 1_{h} `α`_{m}- is the reduction factor for number of members:
`α`= √0,5(1 + 1/_{m}`m`) `l`- is the length or height [m], see § 5.2 (6)
`m`- is the number of vertical members contributing to the total effect, see § 5.2 (6).

This application calculates
the inclination `θ _{i}`
from your inputs.
Intermediate results will also be given.
