Placing Geometric

Data of Foundation

In this activity you will;

Make New Structure.

Before making new structure, be sure the AFES Program is

installed and running to your computer. Click File menu thenselect New/Open Project or just click button.

Choose Code and input unit to use. Example, ACI_IMP American Concrete Institute Code with Imperial as input unit.

Note that all available output is in Imperial unit.

Add New Node.

Node represents the number of pier or pedestal regardless ofthe number of footings.

Before you start this activity, you must be in the ACI_IMP project.

2. Click Addbutton 6 times continuously.

Clicking Addbutton once made it possible to add one node.

3. Enter coordinate values in the spread box.

You can set reference point you want. It is possible to place onepier to be at the origin, or the center of footing, etc.

4. Select Savebutton.

Be sure to always click save button if you want to save up to the

latest development of your model.

The form will show array of 6 nodes according to entering users input.

Setting Foundation

GroupYou need to group foundation to reduce input data and save time

of modeling. For example, you can group foundations with the same

load combinations so you dont need to set again for every footing.


Make Group of Isolated without Pile.

Make Group of Block without Pile.

Make Group of Octagonal with Pile.

Before you start this activity, you must have 6 nodes with geometry

data .

17. Enter the values of wind load as shown below.

Be careful when you enter the values of force/Moment by axis.

For example, Fx = 10 means that the external horizontal load is

applied from west to east having 10 kips. If the direction of externalhorizontal load is from east to west, value of Fx should be -10.

You should decide plus or minus sign of moment by the law of

Fleming.
