The PCF_SIF_MAP.TXT file defines the CAESAR II SIF data to be applied at the intersection of tees and olets. The file also provides support for some SIF keywords.

Stress Intensification Factors (SIF) are not assigned a separate PCF COMPONENT-ATTRIBUTE or defined in any other way inside PCFs. In order to tune Stress Intensification Factor settings of imported PCF components, CAESAR II provides the PCF_SIF_MAP.TXT mapping file.

The file defines five columns:

  • SKEYS - PCF components use SKEYS to indicate how their subtype is used within the general component group.

  • CAESAR II SIF TYPE - Should be set to the SIF type number used by CAESAR II as shown in the CAESAR II SIF TYPE figure below.

  • PAD=X.X UNITS - (optional) Should be set to the SIF pad thickness, including the applicable unit (for example, PAD=10 MM)

  • Ii=X.XX - (optional) Should be set to the in-plane SIF of the component. This is a multiplier, and therefore unit-less (for example, Ii=1.23)

  • Io=X.XX - (optional) Should be set to the out-plane SIF of the component. This is

CAESAR II SIF TYPE figure

Applying the above example values to set the TERF SKEY to the associated reinforced type requires the following mapping entry to be specified inside the PCF_RES_MAP.TXT file:

TERF 1 PAD=10 MM Ii=1.23 Io=2.34

Each PCF component defines an SKEY. For an example, see the SUPPORT component identifier listed in the figure in PCF Restraint Mapping (SKEY 01HG). In this case, these are typically four-character words indicating tee type (CROSS, OLET) and end type. The PCF menu command matches the SKEYS to the entries in this mapping file. If an SKEY is not found in this file, you should add it.

To Modify the PCF_SIF_MAP.TXT File

Locate this file in the CAESAR II system folder.

SHARED Tip This step is strongly recommended in order to take advantage of the capabilities of the PCF menu command.

  1. Open the PCF_SIF_MAP.TXT file in any text editor, such as Notepad.

  2. Modify any of the SIF definitions.

  3. Save, and close the file.
