What's New in GSA 8.6 ?

Key new features:

  • 64-bit hardware support — offering improved performance for large models.

What's New in GSA 8.5 ?

Key new features:

  • New Quad 4 & Triangle 3 element formulations — using MITC (to overcome instabilities in the traditional Mindlin formulation).
  • Orthotropic 2D Elements and Beam Elements
  • Translational Releases and Release Stiffnesses
  • Tied Interface Slave Nodes
  • New Steel Design Codes — EN 1993-1-1:2005 Eurocode 3; IS800:1984; IS800:2007.
  • New RC Slab Design Codes — ACI 318M-08; AS3600-2009; IS456:2000.
  • Unwrap in Graphic Views — allowing 3D structures to be 'unwrapped' into a planar graphical representation.

What's New in GSA 8.4 ?

Key new features:

  • Piled Raft Analysis — extending the existing raft analysis capability to include pile-soil interaction.
  • Bridge load optimisation analysis to Eurocode — and update to Australian code.
  • Environmental Impact — allowing the assignment of environmental impact cost to materials to provide a total environmental cost of the structure. Data is provided to suggest appropriate values for the material type, grade and country.
  • Tied Interfaces — A tied interface constrains a list of slave elements to act as if connected to a list of master elements. A typical use of a tied interface is to zip together adjacent areas of 2D element mesh.
  • Batch saving of views — allowing several saved views to be saved to file in one operation.
  • Explicit entity colour definition — allowing colours to be assigned to elements, properties, materials, and stages.

A graphical summary of the new features in this version may be viewed in the GSA 8.4 New Features PowerPoint presentation.
