SAFE Latest Version: V22.2.0
OVERVIEW
SAFE is the ultimate tool for designing concrete floor and foundation systems. From framing layout all the way through to detail drawing production, SAFE integrates every aspect of the engineering design process in one easy and intuitive environment. SAFE provides unmatched benefits to the engineer with its truly unique combination of power, comprehensive capabilities, and ease-of-use.
Laying out models is quick and efficient with the sophisticated drawing tools, or use one of the import options to bring in data from CAD, spreadsheet, or database programs. Slabs or foundations can be of any shape, and can include edges shaped with circular and spline curves.
Post-tensioning may be included in both slabs and beams to balance a percentage of the self-weight. Suspended slabs can include flat, two-way, waffle, and ribbed framing systems. Models can have columns, braces, walls, and ramps connected from the floors above and below. Walls can be modelled as either straight or curved.
Mats and foundations can include nonlinear uplift from the soil springs, and a nonlinear cracked analysis is available for slabs. Generating pattern surface loads is easily done by SAFE with an automated option. Design strips can be generated by SAFE or drawn in a completely arbitrary manner by the user, with complete control provided for locating and sizing the calculated reinforcement. Finite element design without strips is also available and useful for slabs with complex geometries.
Comprehensive and customizable reports are available for all analysis and design results. Detailed plans, sections, elevations, schedules, and tables may be generated, viewed, and printed from within SAFE or exported to CAD packages.
SAFE provides an immensely capable yet easy-to-use program for structural designers, providing the only tool necessary for the modelling, analysis, design, and detailing of concrete slab systems and foundations.
MODELLING
TEMPLATES
SAFE offers a variety of templates for quickly starting a new model including flat slabs, two-way slabs, basemats, waffle slabs, ribbed slabs, and single or combined footings.
MODEL VIEWS

DRAWING TOOLS
Many drawing and drafting utilities are built into SAFE to enhance the engineer’s modeling experience. Users will find that many of the common industry standard shortcuts and controls are also available in SAFE.

OBJECT BASED MESHING
Object based meshing generates meshes based on the specified maximum element size. It will mesh parallel and perpendicular to the longest edge, grid system, or area local axes and will aim to maintain good element aspect ratios.
DIMENSION LINES
Dimension lines can be drawn on the SAFE model in both architectural or decimal units. They are linked to the objects that they are referencing so if the size of the object changes, so will the dimension line.
Selected Features and Advanced Analysis
BUILT-IN STRUCTURAL COMPONENTS
Foundations, Basemats, and Footings:
SAFE is ideal for modelling foundations, basemats, and footings. Easily model soil supports and zero tension soil models with uplift analysis. The area assignment of soil supports is based on the subgrade modulus, and they automatically adjust whenever the mesh changes. Basemat foundation models can include pedestals, walls, columns, beams, and piles in addition to the foundation area.
Walls and Ramps:
Wall and ramps can be modelled as line loads, line supports, or explicitly modelled with wall elements. Define ridge zones to prevent slab deformations at the wall or ramp location.
Design Strips:
Design Strips:
Design strips are used to define how reinforcement requirements are to be calculated. SAFE can automatically define the strips for you, or you can define them yourself. Orthogonal, non-orthogonal, multi-segment, and varying width design strips are all supported by SAFE.
Insertion Points:
Insertion points are used to define offsets for beams and columns. They can either be defined on quick SAFE defined cardinal points or based on user-defined dimensions.
Post-Tensioning (P/T):
SAFE includes the ability to define post-tensioning in slabs, as banded or distributed tendons. An interactive tendon editor simplifies the task of laying out the tendon profiles. Tendon layouts can also be automated based on strip position and direction.

ADVANCED NONLINEAR ANALYSIS, CRACKED ANALYSIS, CREEP AND SHRINKAGE
SAFE performs a full 3-Dimensional linear static analysis. Advanced Nonlinear analysis such as iteration for uplift, Nonlinear cracked analysis and Nonlinear cracked analysis with creep and shrinkage.
DEFLECTION CONTROL
Deflection control can be performed using a nonlinear analysis or a long-term cracked analysis which takes in to account concrete creep and shrinkage.
DYANAMICS
Dynamic analyses can be performed using either Ritz or Eigen Vectors. Response spectrum loads and modes can be directly imported from ETABS.
DESIGN AND REPORT
STRIP BASED DESIGN
SAFE will calculate the minimum reinforcement requirements of area, intensity, or number of bars. Design will be performed at multiple stations. Design strips can be non-orthogonal and of varying width.
