Significant enhancements included in SAFE 2014 (v14.0.0):

  • Reinforced and Prestressed concrete design have been added for the ACI 318-11 code.
  • Reinforced and Prestressed concrete design have been added for the Italian NTC 2008 code.
  • Reinforced and Prestressed concrete design has been added for the Turkish TS 500-2000 and TS 3233-1979 codes.
  • Reinforced and Prestressed concrete design have been added for the Hong Kong CP 2013 code.
  • The specified concrete strength as used for Chinese materials and design codes has been comprehensively changed for SAFE 2014 to refer to the characteristic strength, whereas in SAFE v12 the concrete strength referred to the grade.
  • Design-strip widths can now be imported from DXF/DWG files.
  • The import and export of AutoCAD 2013 and 2014 *.DWG files is now supported.
  • Import from and export to Revit Structure 2014 is now available using CSiXRevit 2014. Models can be created in SAFE or Revit Structure, and incremental import and export are supported.

Significant enhancements included in SAFE v12.3.2 are:

  • For the Australian code AS 3600-2009, Equation 8.1.3(2) has been changed for reinforced concrete and PT design according to Amendment No. 1 to AS 3600-2009.
  • The enforcement of minimum shear links now recognizes the slab separately from beam. Previously, minimum shear links were enforced for both beam and slab design. This enhancement affects all design codes.

Significant New Enhancements

  • The National Annex to Eurocode 2 has been implemented for Denmark, Finland, Norway, Slovenia, and Sweden for reinforced and post-tensioned concrete design using “Eurocode 2-2004”.
  • The Chinese concrete design code has been updated from GB 50010-2002 to GB 50010-2010.
  • The Australian code "AS 3600-2009" has been added for the design of reinforced and prestressed-concrete beams and slabs.
  • The automatic load combinations created for design by Eurocode 2-2004 now include snow loads when these are present in the model.
  • The thin-plate formulation has been added as an option for slab sections. The thick-plate formulation is the default and the recommended option. The thin-plate option is provided primarily for comparison purposes, especially with theoretical results. The thick-plate option generally provides better forces for design.
  • The sign of all results for hyperstatic load cases has been reversed to be consistent with common usage.
  • An enhancement was implemented allowing the program level (i.e., STANDARD, PT, etc.) to be chosen when starting the program.

Significant New Features

  • New drafting controls have been added for drawing curved edges of area objects.
  • Graphical display of crack widths has been added for reinforced-concrete slab   regions. The calculation is based on Section 7.3.4 of Eurocode 2-2004,   regardless of the code chosen for design.
  • The punching-shear check is now performed at the edges of drop panels for all cases where drops are present. Previously it was restricted to locations where columns were specified.
  • The slab punching design check on the maximum shear for which stud rails or steel reinforcement can be provided has been reinterpreted to be based on the average shear around the perimeter. Previously this check was using themaximum shear around the perimeter. This change will now allow for more designs to pass where reinforcement is provided.
  • The Detailer has been enhanced to produce a Footing Bill of Quantities, providing a table of the total rebar quantities for footing-type area objects.
  • User control has been added for the convergence tolerance used for nonlinear   analysis. Although this is rarely needed, it allows more flexibility for handling   sensitive uplift and cracking cases.

Significant New 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 models can 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.
  • The Architectural Layer tracing for importing DXF/DWG files has been significantly enhanced for object recognition, speed, and ease of use.
  • Dimension lines now automatically adjust with the movement of associated grid lines and objects.
  • Tendon high and low points are shown in plan views as distances from the top or bottom of the slab.
  • T-beams and L-beams can now be explicitly specified as being inverted.
  • Wide beams can now be converted to equivalent thicker slabs when desired.
  • Temperature loading has been added, including the ability to specify different   temperatures above and below the slab (temperature gradient).
  • Distributed lateral forces and moments can now be applied to beams, and   distributed lateral forces can be applied to slabs. These lateral loads can also be   imported from ETABS.
  • Analysis of cracking deflection has been enhanced to include the effects of creep, shrinkage, and axial loads.
  • Design combinations can easily be converted to nonlinear load cases for uplift calculation.
  • Integrated wall forces are now reported as reactions.
  • Distinct middle and column design strips have been implemented for R/C design,   which improves design reporting and detailing. Full-width column strips are normally used for P/T design.
  • User-specified reinforcement may be defined. Design can take this into account and report the additional rebar needed, if any, to meet code requirements.
  • Punching-shear design has been enhanced to account for edges and corners, with user overwrites provided for additional control.
  • One-way shear design has been added to the design strips for all codes.
  • For design using FEM results (rather than design strips), the effect of P/T upon   strength design has now been implemented. FEM-based design is an effective   alternative to strip-based design when strips cannot be easily or reasonably defined.
  • The effect of P/T upon design can now be ignored in local regions for both strip-based and FEM-based design.
  • The automation and user-control of beam sections used for analysis and design has been enhanced to better consider the interaction with the slab.
  • Chinese design code and language translation have been implemented for users with a Chinese license.
  • Usability, control, and reporting have been significantly enhanced for the Detailer, including single-level Undo/Redo.
  • A comprehensive set of keyboard shortcuts has been added for power users.
  • Overall enhancements for usability, speed, look and feel have been implemented throughout the program.

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.
