Reinforcement Tensile Strength
Long-term design strength of geo-reinforcement Rt is calculated from the input parameters of the geo-reinforcement:
- Standard calculation:
where: | Rt | - | long-term design strength of reinforcement |
Tult | - | short-term characteristic strength of geo-reinforcement | |
RFCR | - | reduction coefficient of long-term deformation of reinforcement (determined based on geo-reinforcement lifetime) | |
RFD | - | reduction coefficient of the durability of reinforcement (determined based on soil pH) | |
RFID | - | reduction coefficient of failure of reinforcement when inserting into the soil (determined based on the grain sizes of soil) | |
FSUNC | - | overall coefficient of model uncertainty |
Note: The FSUNC coefficient is not taken into account when calculating the reinforcement strength in the "Redi-Rock Wall" program.
- according to EBGEO (only in the MSE Wall program):
where: | Rt | - | long-term design strength of reinforcement |
Tult | - | short-term characteristic strength of geo-reinforcement | |
A1 | - | reduction coefficients of long-term deformation of reinforcement | |
A2 | - | reduction factor of damage during the installation | |
A3 | - | reduction factor of processing (seams, connections, joints) | |
A4 | - | reduction factor of environmental influences | |
A5 | - | reduction factor of dynamic effects |
