Member loads are defined for the element(s). 2. Element properties for the plane curved elements are defined using the section property specifications and giving values for AX and IZ only. Workarounds: Workarounds for the problem include specification of an arbitrary value for the IX section property or using the TABLE option for the specification of the curved element properties.

Swanger January 5, 1996 Typed or Printed Name Date of Signature Signature Title Professional Services Division Typed or Printed Name Date of Signature Rev. 2.2 GTSTRUDL Program Report Form (Continued) GPRF No.: 96.02 DATE: January 5, 1996 DESCRIPTION: The SOLVE FOR FATIGUE command will not execute to completion and compute joint displacements if preceded by an eigenvalue analysis. This will not be evident until a COMPUTE FATIGUE command is given, in which case the following error message will be printed: ****ERROR_STFCHK -- COMPUTE FATIGUE RESULTS NOT POSSIBLE. FATIGUE SOLVE NOT YET PERFORMED. Workaround: eigenvalue analysis results are not needed in the same job that performs a fatigue analysis which includes the SOLVE FOR FATIGUE and COMPUTE FATIGUE commands. Therefore, perform the eigenvalue analysis and fatigue analysis in separate jobs. Furthermore, do not perform a fatigue analysis in a job that restores a save file that contains the results of an eigenvalue analysis. If the eigenvalue analysis and the fatigue analysis use the same structural model, use the same sequence of commands that define the model (JOINT COORDINATES, MEMBER INCIDENCES, MEMBER PROPERTIES, etc.) in both the eigenvalue analysis job and the fatigue analysis job.
