Pile Wall with Steel Cross Section
The Pile wall with steel cross section requires input of:
- Cross section name (default name is generated by program, it can be changed using "User def." check box)
- Coefficient of pressure reduction below ditch bottom - this coefficient is used for reduction of pressures below ditch bottom for calculation of braced sheeting - it can be either input or calculated automatically (for classical non-braced sheeting this coefficient is equal to 1.0)
- Cross section type (circle, square)
- Pile diameter d and their spacing a
- Steel cross section (I-section, pipe, 2xU-section or welded) is selected in the dialog window "Catalog of profiles" (button "Catalog")
Parameters input - pile wall with steel cross section
For the calculation of cross-sectional characteristics the steel section is converted to concrete.
where: | Ic | - | moment of inertia of concrete cross-section |
Ec | - | elasticity modulus of concrete | |
Kc | - | correction factor for concrete | |
Is | - | moment of inertia of steel cross-section | |
Es | - | elasticity modulus of steel | |
Ac | - | cross-sectional area of cocnrete | |
As | - | cross-sectional area of steel | |
a | - | pile spacing |
