Internal Stability Tab

 

Displays internal stability table:

 

Layer:                Displays geogrid layer numbers.

 

Height, ft:        Displays the height from the base to the elevation of each geogrid layer.

 

Trib Height:        Displays the tributary height of each geogrid layer.

 

Depth to Midpoint:        Displays the distance from the top of the wall to each geogrid layer.

 

Tension from Soil:        Displays the tension in each layer of geogrid due to lateral earth pressure from the soil.

 

Tension from DL Surcharge:        Displays the tension in each layer of geogrid due to lateral earth pressure from a dead load surcharge.

 

Tension from LL Surcharge:        Displays the tension in each layer of geogrid due to lateral earth pressure from a live load surcharge.

 

Static Total Tension, Fg:                The sum of Tension from Soil plus Tension from DL Surcharge plus Tension from LL Surcharge.

 

LTDS:                                Echoes the Long Term Design Strength of the selected geogrid.

 

LTDSseismic:                                Echoes the Long Term Design Strength for seismic design of the selected geogrid.

 

Total Tension (w/ Seismic), Fi:        Total tension in the geogrid when subjected to the load condition that includes seismic loading.

 

FS Tensile Overstress (static):        LTDS / Static Total Tension

 

FS Tensile Overstress (w/ seismic):        LTDSseismic / Total Tension (w/ seismic), Fi

 

Pullout Strength:                        Ability of the geogrid to resist pullout failure.

 

FS Pullout (static):                        Pullout Strength / Static Total Tension, Fg

 

FS Pullout (w/ seismic):                Pullout Strength / Total Tension (w/ seismic), Fi

 

Connection Strength:                Connection strength of the selected block/geogrid combination.

 

FS Connection (static):                Connection capcacity / Static Total Tension, Fg

 

FS Connection (w/ seismic):        Connection capcacity / Total Tension (w/ seismic), Fi

 

Internal Sliding Force (static):        The driving force at each layer of geogrid from static loading tending to cause the soil mass above to slide sideways.

 

FS Internal Sliding (static):        Internal sliding resistance / Static internal sliding force

 

Internal Sliding Force (w/ seismic):The driving force at each layer of geogrid from loading including seismic tending to cause the soil mass above to slide sideways.

 

FS Internal Sliding (w/ seismic):        Internal sliding resistance / Internal sliding force (w/ seismic)
