Starting Out

To start an embedded post design first click on the embedded post design module icon located in the design module dropdown in the upper right of the screen next to your username.

This will load the embedded post design module, which loads with a preset template.

The following steps do not have to be completed in this order and are designed to work dynamically with each other, so don't worry if you realized later you clicked the wrong thing or made a mistake, just change that item and the rest will follow suit accordingly.

Set the Properties

SECTION CONTENTS

• The Basics
• Embedded Post Specific Selections
• Column Specific Selections
• Solid Sawn & MSR/MEL Selection
• Glulam Selection
• Steel Selection

The Basics

On the left side of the screen is the Properties tab, work progressively from top to bottom to specify the desired properties. The template is used to set predetermined properties. As you move down the properties new selection dropdowns will appear based on previous dropdown selections. Examples of this can seen for any of the material selections. When Steel is selected as the material, a different set of properties selections are available.

At the top of the properties tab is the LRFD/ASD design options, as well as the dry or wet factors button. The pictures above shows LRFD and Dry. The picture below shows ASD and wet. Click the icons to toggle back and forth between the two options for each.

Embedded Post Specific Selections

• Footing Dimensions
  • (Width) Input or select the footing width in feet.
  • (Depth) No need to input anything here. After calculating the text box will show the minimum required embeddment depth in feet.
• (Bearing Pressure) Input the lateral bearing pressure.  More information on values can be found in the International Building Code (IBC) Table 1806.2  
• (Restrained) Select if the post is restrained by a rigid floor or slab at the ground surface
• (Soil Pressure Doubled) Select for a lateral bearing increase for flagpoles or signs not adversely affected by 1/2 inch of of motion at the ground surface. See IBC 1806.3.4 for more information.
• (Round Footing) Select if the footing is round.

Column Specific Selections

• (Load Eccentricity (X-Axis)) Input an eccentricity to be applied to the load, on the x-axis
• (Load Eccentricity (Y-Axis)) Input an eccentricity to be applied to the load, on the Y-axis
• (Auto-Calculate End Condition) Determines the Ke factor based on the end conditions, if unchecked, select the gear icons next to each end condition input box and use the end condition popup to select the desired Ke, see image below.
  • End Condition - Ke (x)
  • End Condition - Ke (x)

• (Auto-Calculate Stability Factor) Calculates stability factor, uncheck to input a different value.
• (Cantilever Column) Applies the properties associated with a cantilever column design. For this module it is locked to checked.

Below is a list of the properties selections based on the material type. Use each of these to guide you through the selection process.

Solid Sawn & MSR/MEL Selection

• (Species) Select the species of wood
• (Grade) Select the grade of lumber *can be skipped for autosize
• (Include Self Weight) Check for including the self weight of the member

Size

• Input or select the number of laminations, width, depth of the column *can be skipped for autosize

Options

• (Round) Select if the column is round, if selected the size option will revert to a radius only instead of width and depth

Factors

• (Temperature Factor) Select the temperature range of the design
• (Apply the Incising Factor) Select to include the incising factor
• (Include Creep Factor) Apply to include the creep factor

Glulam Selection

• (Stress Class) Select the stress class
• (Grade) Select the grade
• (Include Self Weight) Check for including the self weight of the column

Size

• Input or select the number of laminations, width, depth of the column *can be skipped for autosize

Factors

• (Temperature Factor) Select the temperature range of the design
• (Include Creep Factor) Apply to include the creep factor

Structural Composite Lumber (SCL) Selection

• (Species) Select the SCL manufacturer
• (Grade) Select the SCL product/size

Size

• Input or select the number of laminations, width, depth of the column *can be skipped for autosize

Factors

• (Temperature Factor) Select the temperature range of the design
• (Include Creep Factor) Apply to include the creep factor

Steel Selection

• (Shape) Select the shape
• (Size) Select the size of the shape
• (Grade) Select the grade of steel

Below is an image of the entire properties tab if Steel is selected as the material.

Edit Reactions 

Editing reactions is not possible in this design module.

Adding Loads

After the materials, properties, spans, and reactions of the column are chosen move to the middle panel of the screen to start the loading process. 

Here you can add any type of load listed on the left hand side of the middle panel as shown in the image below (Distributed, Trapezoidal, Point, Axial, Moment, and Linked). 

Once a load icon is selected an input box will appear where you can enter the loading data. As shown in the example "Add Axial Load" input box, the load axis is locked to the Z axis and the load can be a point or distributed. 

After load input click "Add" and the load will be added to the column.

Once the load is added it can be manipulated in two different ways.  You can change the load by clicking on it which will bring back the load input box or you can change the load by locating the loads tab on the bottom of the screen.   

To add an out of plane load simply change the axis on the load input box or in the load cards. Select the axis icon in the upper left corner of the load screen to switch the view and see the out of plane loads.

Another useful tool is the toolbar located between the location name and the loading screen.

Each icon corresponds to a load type, the furthest left icon shows all load types. Clicking any of the others will only show loads of that specific type.

Calculators

The toolbar on the right side of the loading screen is where the calculators are located. These are some handy tools used to facilitate a faster design process, and save you time!

From top to bottom the calculators are as follows:

Dead Load Calculator

Add dead loads to your module.

Tributary Area Calculator

Use the input boxes to enter the load type (the load axis is locked to the Z direction), load psf value for the tributary area, and the tributary area for the post. The resulting load will be added to the embedded post accordingly.

Calculate

Once the embedded post is loaded you can hit enter to calculate or click the calculate icon located above the properties tab on the right hand side.

From left to right the buttons are Calculate, Autosize, and Save. After calculating the Print Preview icon will appear.

Auto Size

Using the Autosize function can be done dynamically, but following this order is good for first time users.

1. These two buttons are check all and uncheck all respectively, use these to select or deselect all the grades.
2. Check to ensure the sizing properties are okay and make any changes based on your desired design. Input any restrictions to limit the results.
3. Use the button below the grades run the autosizer and select the size and grade which best suits your design.

Results

After calculation the adequacy cards will appear in the lower toolbar across the bottom of the screen. Additionally the minimum depth of embeddment will be returned as the footing depth in the properties tab.

If any of the calculations fail, the percentages will turn red. The controlling load combination is shown directly under the adequacy percentage. Clicking the load combo will result in showing the corresponding diagrams on the right side of the screen. The dropdown showing the load combo can be switched to any of the load combinations used in the calculations. The quick view can be switched to any of the loaded axis as well.

After successfully calculating, the print preview icon will appear in the top toolbar and clicking it will bring up the .pdf report generated for the design.
