Starting a new project

When the software starts it will always display a new empty project. In order to begin entering CPTU data you must first define the unit system that you wish to use. By default CPeT-IT uses the SI unit system. Defining the unit system prior to inserting any data will allow you to easily switch between the supported unit systems, applying automatically all required transformations.

In order to define the unit system, click on the Project properties button button located on the main toolbar. The following dialog will appear:

Project properties

Using the above dialog you can insert or modify settings regarding the project's general information. For example, you can enter the Project Title and the Test Location (both not to exceed 150 elements, since they appear on the Plots).  Comments will not appear on the Plots. When the dialog opens it will display any previous data entered before. From the Unit system drop down list you can specify the unit system you wish to use. Below the drop down list the software will display the units that will be used for data importing and interpretation. These units are:

Unit System

Depth

Cone resistnace

Friction resistance

Pore pressure

Unit weight

SI

meters (m)

Megapascal (MPa)

Kilopascal (kPa)

Kilopascal (kPa)

Kilonewtons per square meter (kN/m³)

Imperial

feet (ft)

Tons per square foot (tsf)

Tons per square foot (tsf)

Pounds per square inch (psi)

Pounds per cubic foot (pcf)

The units used are fixed and cannot be changed in any way thus your input data must fully comply to this specification. During the import procedure CPeT-IT will assist you in order to convert your input data to meet the above units.

Zoom direction is used to specify how the software will handle zooming inside the plots (by left click and drag inside the plots area). Setting this option to Both will instruct the software to try and fit left and bottom axes according to the rectangle drawn during the click and drag mouse movement. Vertical direction (selected by default) will only adjust the left axes of the plots.

Vertical axis of a plots can be set to display depth data as a function of the penetration depth or elevation. If you have previously fixed the vertical axis scale changing this option may result to an empty plot so make sure you check Y axis scale (min and max values) prior to any change. Elevation data are only visible to plots where all calculation data and results will appear displaying the penetration depth of each CPT point.

To commit any changes made you must click on the OK button. If you click on the Cancel button no changes will be made.

Use the Company Information Tab to input your company logo, name and address, which will appear on all future reports.
