Version 28.1Dynamic Analysis Eigenvalue
Performance
  • A new version of the out-of-core GTLANCZOS
    Eigenvalue analysis solver called GTHCLANCZOS has
    been implemented. 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.

16
Version 28.1Dynamic Analysis Eigenvalue
Performance (cont)
  • Bandwidth 1179
  • Joints 39765
  • Members and Elements 46587
  • Number of Modes 100
  • Solution data for GTHC-LANCZOS Solver
  • Number of dynamic degrees-of-freedom 236640
  • Number of modes requested 100
  • Eigenvalue tolerance

  • Average column height of skyline 4699
  • Number of hypercolumns 112
  • Rank of mass matrix 236640
  • Number of Lanczos vectors computed 187

17
Version 28.1Area Load Error Detection
  • Error checking for illegal member configurations
    such as X-bracing and overlapping members has
    been improved.

18
Version 28.1Statistical 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.

19
Version 28.1Offshore
  • 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.

20
Version 28.1Steel 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.

21
Version 28.1Steel 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
    sections 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.

22
Version 29
  • Undergoing limited Beta testing now
  • Will undergo final testing in August
  • Target date for release October 2006

23
Model Wizard
  • A Tangent option has been added to the the Tank
    Wizard to allow for a smooth transition from the

    added to the Rectangular Tank Wizard
  • The new CQSHELL6 element has been added to the 2D

    increases the size of the Eigenvalue problem that
    can be solved in-core. To date, we have
    successfully solved eigenvalue problems having
    330,000 DOFs. A problem with around 240,000

    SOLVER command is used.
  • These improvements include the ability to
    store and retrieve results data limited only by
    the amount of hard drive space available. In
    addition, improvements are also being made to the
    efficiency of the maximum value file search
    algorithm used for the LIST TRANSIENT MAXIMUM and
    CREATE PSEUDO STATIC LOAD FROM MAXIMUM commands.

Future Enhancements
119
Future Enhancements
  • Graphically specify Area Loads in GTMenu
  • Allow a 2-point line to be specified using "Start
    and End" mode, as for Member generation.
    Currently "End to End" mode is assumed.
  • Expand the Member and Element generation Spacing
    option, "Defined by Line/Curve", to accept an
    n-point line of up to 500 segments. Currently it
    is limited to 50 segments

120

    separate window than the model display
  • Graphically specify joints and elements to be
    used with LIST SUM FORCES command
  • List the contents of a Group in an Inquire box.
    Currently the contents can only be displayed
    graphically

121
Future Enhancements (cont)
  • Add a Display Options capability to the Principal
    Vector display for principal stress vectors
    similar to the one shown here for contouring

122
Future Enhancements (cont)
  • Add the option to Split Members to interpolate
    eccentricities between the start and end of the
    split members
  • Ability to click on a member and have a graphical
    summary of the results on just that member in a
    separate Window that can be printed

123
Future Enhancements (cont)
  • Addition of the following items to the input file
    created by GTMenu
  • Dynamic Loadings
  • Eigenparameters
  • Dynamic Modal Damping Data
  • Nonlinear Effects
  • Nonlinear Spring Properties
  • Nonlinear Solution Parameters
  • Cable Network Data

124
Future Enhancements (cont)
  • Add the ability to graphically display rigid
    bodies, joint ties, slave releases, and
    superelement data (we need input on this)

125
Future Enhancements (cont)
  • Latest ACI 318
  • AISC 13th edition (ASD LRFD)

126
Future Enhancements (cont)
  • Torsion and Warping check or design for ASD9 and
    LRFD3 codes.
  • Cross-sections considered for ASD9 code
    are
  • I shapes, Channels, Single Angles, and
    Structural Tubes
  • Cross-sections considered for LRFD code are
  • I shapes, Channels, Single Angles, Pipes, and
    Structural Tubes

127
Future Enhancements (cont)
  • Warping stress computations will be based on
    Cases 1 and 2 of the Torsion Analysis of Rolled
    Steel Section by Bethlehem Steel or the AISC
    Torsional Analysis of Structural Steel Members,
    Steel Design Guide Series 9. The following
    boundary conditions will be implemented
  • FIX-FIX, FIX-PIN, PIN-FIX, PIN-PIN

128
Future Enhancements (cont)
  • Add maximum moments and/or forces to the user
    specified sections for code check or design.
    User can specify from the maximum of FX, FY, FZ,
    MX, MY, MZ, or all of them. When user specifies
    maximum force or moment, the maximum locations
    are added to the list of sections that the user
    has already specified.

129
Future Enhancements (cont)
  • Add an option to code check and design for a
    maximum envelope. This means first finding the
    maximum FX, FY, FZ, MX, MY, and MZ. These
    maximums are then assumed to act at a single
    location for the code check or design.

Your assistance is needed to help us improve
GTSTRUDL in the Committee meetings tomorrow
  • Please provide us with a prioritized list of the
    features that you would like to see. Please be
    specific especially when requesting model wizard,
    design codes (which codes and which cross
    sections) or datasheet requests.
  • Sketches of wizards, output, and graphical
    displays help us tremendously.

137
Committee Reports
  • We need details regarding features that you
    request. Despite our best attempts to take notes
    and remember what was said in the committee
    meetings, we often have trouble understanding
    your requests when we review the Committee
    Reports. Please be specific and provide as much
    detail as possible.
