Analysis Options:

Include Pedestal: Check if the strip footing contains a pedestal which the wall sits on.

Subgrade Soil Type: Selected the type of soil the subgrade sits on (changes bearing pressure calculation).

Load and Resistance Factors:

Load Factors: Inputs to allow manual override of the load factors.

Resistance Factors: Inputs to allow manual override of the resistance factors.

Physical Dimensions:

Wall Thickness: The width of the keyway on the top of the strip footing.

Pedestal Width: The width of the pedestal.

Pedestal Height: The height of the pedestal.

Slab Width: The width of the strip footing.

Slab Thickness: The thickness of the strip footing.

 Slab Length: The total length of the strip footing.

Concrete Properties:

Weight: The unit weight of the concrete.

Strength: The compressive strength of the concrete.

Elastic Modulus: The elastic modulus of the concrete.

Aggregate Size: The aggregate size of the concrete.

Soil Properties

Weight: The unit weight of the soil.

Bearing Strength: The bearing strength of the soil.

Inner Fill: The inner fill height of the footing.

Outer Fill: The outer fill height of the footing.

Sliding Friction Angle: The angle of friction between the footing and the subgrade.

Reinforcement Properties

Yield: The yield strength of the reinforcement.

Elastic Modulus: The elastic modulus of the reinforcement.

Reinforcement Type: Two options which choose whether to use rebar or mesh for reinforcement.

Rebar / Mesh Type: Displays a list of all available reinforcement types supported by the strip footing analysis. These include US Customary, Soft Metric, and Canadian.

Flexural Reinforcement:

Auto Design: If checked Eriksson Culvert will pick a bar size and spacing from the reinforcement library.

Bottom Long. Reinforcement:

Bar Size: The bar size of the reinforcement for the selected area.

      Spacing: The spacing of the reinforcement for the selected area.

Cover: The cover of the reinforcement for the selected area.

View Reinforcement Library: Click to access the size/spacing pairs library available in Eriksson Culvert.

Loading Conditions

Contains to drop down boxes which contain all of the truck/fill depth combinations from Eriksson Culvert.

 Add: Expands the input to allow the definition of a new load.

Edit: Expands the input to allow for editing of the currently selected load in the list.

Delete: Deletes the currently selected load.

The interface for the input of a new load. These loads are assumed to be point loads acting at the center of the strip footing on the top surface.

Load Type: A drop down box for selecting the type of load.

X Component: The x-component of the applied load.

Y Component: The y-component of the applied load.
