GTHCLANCZOS does less to improve efficiency than it does to significantly increase the size of the eigenvalue problem that can be solved. An example of the solution of an eigenproblem with 240,000 dof is shown on the next slide.

Version 28.1Area Load Error Detection: Version 28.1 Area Load Error Detection Error checking for illegal member configurations such as X-bracing and overlapping members has been improved.

Version 28.1Statistical Output for the GTHCS static solver: Version 28.1 Statistical Output for the GTHCS static solver The statistical output for the GTHCS solver now includes output regarding the numbers of dof, the number of terms in the skyline, and the number of hyper-columns.

Version 28.1Offshore: Version 28.1 Offshore The Efthymiou SCF equations for the computation of stress concentrations have been added to the FATIGUE MEMBER command for offshore fatigue analysis. The FATIGUE MEMBER command now provides for the selection of the Kuang, Smedley, and Efthymiou SCF equations.

Version 28.1Steel Design: Version 28.1 Steel Design A new parameter called ‘Class3' has been added to EC3 code. This parameter allows the user to request that the code check or design to be performed based on the class 3 classification. A user specified value of ‘YES’ for this parameter indicates that when a code check or design is performed for EC3 code, equations based on the Class 3 classification should be used.

Version 28.1Steel Design (cont): Version 28.1 Steel Design (cont) The SUMMARIZE command for the critical section prints the summary results for the section that has the highest actual/allowable ratio. When the KL/r actual/allowable ratio is the highest ratio during a code check or design, the SUMMARIZE command for the critical section outputs that section’s summary results. In general, prismatic sections have the same KL/r ratio for each loading and section. Since the KL/r value is the same for all sections, when the SUMMARIZE command is issued and the KL/r is the highest actual/allowable ratio, the summary results for the last loading and last section are printed. In this version of GTSTRUDL, the summarize output for the critical section has been modified to also print the section with the highest stress value. The section which has the highest stress value also has the highest KL/r ratio.

Version 29: Version 29 Undergoing limited Beta testing now Will undergo final testing in August Target date for release – October 2006
