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
