Show me Nonlinear Shearwall capabilities

• A nonlinear, layered shell element using a directional material model has been added for pushover analysis of shear-wall structures and similar applications. A Quick-Start option is provided for easy modeling of reinforced concrete sections.
• Plot functions have been added for shell layer stresses.
• Frame hinges for Section Designer sections “To be Designed” have been enhanced to use the designed amount of rebar when available.
• Section Designer has been enhanced for the display of fiber-model PMM surface.
• The default material properties for concrete have been modified to improve convergence behavior.
• The tangent stiffness used for the iteration of fiber hinges and multi-linear links has been changed to improve convergence. Video için tıklayınız:   

• Material-based damping is now available for linear and nonlinear direct-integration time-history analysis.
• Material-based damping is now available for steady-state and PSD analysis.
• Stiffness-proportional damping now uses initial stiffness instead of tangent stiffness to improve the consistency of results and convergence behavior.
• The rigid-response calculation in response-spectrum analysis has been enhanced for NRC and general use.
• Base reactions for response-spectrum and modal time-history analysis have been improved for springs and grounded link supports to better capture missing-mass effects.
• Base reactions no longer include constraint forces at restraints, for consistency.

• Processor: Minimum: Intel Pentium 4 or AMD Athlon 64. Recommended: Intel Core 2 Duo, AMD Athlon 64 X2, or better (see notes 1 and 2 below)
• Operating System: Microsoft® Windows XP with Service Pack 2 or Microsoft® Windows Vista, 32- and 64-bit versions. (see notes 3 and 4 below)
• Memory: Minimum: 1 GB for XP O/S, 2 GB for Vista O/S. Recommended: 2 to 4 GB for 32-bit O/S, 4 GB or more for 64-bit O/S. (see note 5 below)
• Disk Space: 6 GB to install the program, additional space required for running and storing model files and analysis results.

Show me how Automated Seismic Design of Bridges works

• AASHTO LRFD 2007 superstructure design for precast concrete composite sections has been implemented. Checks include: stress, flexure, and shear (using MCFT).
• Fully automated bridge design check per AASHTO Guide Specifications for LRFD Seismic Bridge
• Design 2009 has been implemented, including pushover analysis when required.
• Automated handling of secondary prestress force has been implemented for the AASHTO LRFD 2007 superstructure flexural design check for prestressed concrete box girder sections.
• The AASTHO/USGS 2007 response-spectrum function has been added. • Variable girder spacing along the length of the bridge superstructure is now available.
• Variable reference-point location along the length of the bridge superstructure is now available.
• Alignment of shell local axes in generated bridge models has been enhanced.
• The longitudinal discretization of bridge models is now more uniform in complex models.
• Tendons modeled as elements now allow elastic, creep, shrinkage, and steel-relaxation losses to be directly specified.
• The displacements for constrained joints in staged construction are no longer updated for deflection until they are actually added to the model.

• Eurocode-2 2004 concrete frame design added, without seismic provisions.
• Eurocode-3 2005 steel frame design added, without seismic provisions.
• Australian concrete frame design per code AS 3600-2001 added, including seismic provisions.
