| Mix Name | The label used to identify a concrete mix. The mix name is not necessarily the concrete strength. Each column, wall, slab and beam has a concrete mix property. |
| Density | The concrete mass density used to calculate various stiffness properties for Concrete. |
| Density for Loads | The concrete mass density used to calculate self weight. |
| f’ci | The characteristic cylinder strength of the concrete mix at the time of applying prestress (also known as initial strength). |
| f’c | The characteristic cylinder strength of the concrete mix.
Note:
f’ci
and
f’c
are used for all codes except BS8110.
|
| fcui | The characteristic cube strength of the concrete mix at the time of applying prestress (also known as initial strength). |
| fcu | The characteristic cube strength of the concrete mix.
Note:
fcui
and
fcu
are only used for BS8110 and IS456.
|
| Poisson’s Ratio | The negative of the ratio of lateral strains to axial strains for an axially loaded material. This is usually 0.2 for concrete. |
| Coefficient of Thermal Expansion |
The concrete coefficient of thermal expansion used to calculate temperature strains. |
| Ec | Calc The method used to calculate Young’s Modulus (for both initial characteristic strength and characteristic strength). This can be according to the active code rules or a specified value. |
| User Eci |
The user-defined Young’s Modulus used for initial cross section analysis. |
| User
Ec
|
The user-defined Young’s Modulus used for global analysis, service cross section analysis and strength design. |
