To start a column design first click on the column design module icon located in the design module dropdown in the upper right of the screen next to your username.
This will load the column 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.
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.
Below is a list of the properties selections based on the material type. Use each of these to guide you through the selection process.
Below is an image of the entire properties tab if Steel is selected as the material.
After the material and properties of the column are chosen move to the middle panel of the screen to edit the column span, reactions, and start the loading process.
To add or remove a span use the + and X icons shown by the image below to add or delete a span on either side.
When the plus button is selected, it will bring up the New Span input box. Type in the span distance you would like to add, specify the top and bottom unbraced lengths, and click save to add the new span. Clicking exit will not add a span and will return to the exact spot before the add span was selected.
To delete a span simply click the X icon below the plus. Additionally spans can be edited and deleted using the span cards on the lower toolbar across the bottom of the screen.
In the middle panel of the screen, the reactions of the column are buttons therefore clicking the reaction itself will bring up the edit reactions input box. Here the available reactions can be selected to be changed based on the desired design. Each reaction icon will update the boundary conditions to correspond with the reaction type.
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.
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:
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 column. The resulting load will be added to the column accordingly.
The wall load calculator is used to quickly add loads from multiple levels above.
Once the column 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.
Using the autosize function can be done dynamically, but following this order is good for first time users.
After calculation the adequacy cards will appear in the lower toolbar across the bottom of the screen.
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.
