SAFE™ v12 - Features & Enhancements


Welcome to SAFE v12 – this all-new SAFE is the ultimate integrated tool for designing reinforced and post-tensioned concrete floor and foundation systems. This version introduces versatile 3D object based modeling and visualization tools. Charged with the power of SAPFIRE this release redefines standards in practicality and productivity.

From framing layout to detail drawing production, SAFE integrates every aspect of the engineering design process in one easy and intuitive environment. Although its name is unchanged, the all-new SAFE is vastly enhanced and improved in every facet. It provides unmatched benefits with its unprecedented combination of power, functionality and ease-of-use.

SAFE v12 is available as SAFE, which includes comprehensive capabilities for reinforced concrete, or SAFE/PT, which additionally includes all post-tensioning features.

  • Meshing options have been simplified and improved to create more efficient meshes that use less memory and increase the speed and accuracy of the analysis and design.
  • The Equivalent Frame Method (EFM) has been added as a tool for designing, 2-D reinforced concrete and post-tensioned frames. Standalone 2-D modelscan be created, analyzed, and designed independently of the current 3-D slab/mat model. Additionally, the geometry and basic properties for the 2-D frame can be extracted from a straight design strip of the 3-D model.
  • Several improvements to the punching-shear design have been made, including:

    1. Automatic detection of interior, edge, and corner locations of the support or load. The user can over-write the location as desired.

    2. Removal of rounded corners from non-circular perimeters except for Eurocode design.

    3. The effect of moments on the shear stress is now computed as specified for each different code.

    4. The effect of slab openings is accounted for automatically.

    5. Punching shear is no longer calculated where beams and walls intersect the punching shear perimeter.

    6. The user can overwrite the effective depth of slab, as well as the size and orientation of the load or support.

  • Models of a single floor exported from SAP2000 v14.1.0 or later can now be imported. This includes linear-static, modal, and response-spectrum load cases, along with their analysis results.
  • The effect of post-tensioning is now considered for the shear and torsion design of beams, leading to a more efficient design. Numerous other detailed, code-based improvements have been made to the shear and torsion design of beams, with or without post-tensioning effects.
  • Graphical rotation in 3-D using the mouse has been enhanced such that rotation will occur about the point on the working plane that is at the center of the screen.
  • More control has been provided for modeling of the support conditions at the top of walls and columns above the slab.
  • Bending (out-of-plane) stiffness of wall supports can be turned off.
  • The model can now be restricted to plate behavior only for those cases where membrane action is not important.
  • The modulus of rupture used for cracked deflection analysis has been improved for both default values and the ability for the user to specify its value.
  • The reported transverse (plate) shear stresses and shear forces have been improved. They are now calculated by equilibrium from moment gradients, rather than from shear deformations as was previously the case. No other analysis results are affected by this change.
  • Superimposed dead loads (SDL) are now included in automatically generated design load combinations.
  • The operations to expand and shrink area objects can now be applied to individual edges.
  • The Project Explorer has been made faster for larger models.
  • The results display forms now remain open so that the load cases and combos, step numbers, components, and other options can be changed without returning, to the menu command.
  • Options have been added to the Detailer that allow certain detailing items to be turned on or off. These can be used to improve performance for larger models.
  • New output tables have been added to provide enveloping response information for displacements, soil pressures, beam forces, and strip forces over each quarter of each span.
  • A new output table has been added to display the design results of the P/T flexural stress check at transfer, normal, and long term conditions.
  • The ability to use a script file is now available to run multiple models in a batch mode for performing analysis, design, detailing, and exporting results.
  • Multiple enhancements have been made to the DXF/DWG import and export:

    1. Strips and tendons are now imported and exported. Grids are now exported to DWG.

    2. Curved and multilinear lines are now exported as a single poly-line rather than a series of lines.

    3. Curved walls are now exported.

    4. Plan and developed elevation are now exported; previously only 3-D views were exported.

    5. Dimension lines are now imported.

  • The shear design for “Eurocode 2 2004” has been enhanced to optimize for angle “theta” in Section 6.2.3 of the code.
  • Auto Pattern Live Load combinations are now included in the default Chinese code design load combinations. They were already included in the default combinations of other codes.
  • The Singapore National Annex to Eurocode 2 (NA to SS EN 1992-1-1 : 2008) has been implemented for concrete and post-tensioned design using “Eurocode 2-2004”.
