## Eurocode 2 part 1-1: Design of concrete structures 3.1.4 (2) and B.1 (1)

The creep coefficient `φ(t,t _{0})` may be calculated from:

φ(t,t = _{0})Φ⋅_{0}β _{c}(t,t_{0}) | (B.1) |

where:

`Φ`_{0}- is the notional creep coefficient
`β`_{c}(t,t_{0})- is a coefficient to describe the development of creep with time after loading.

This application calculates
the creep coefficient `φ(t,t _{0})`
from your inputs.
Intermediate results will also be given.
