SCIA Engineer 15.3



SCIA Engineer 15.3 comes with a set of various extensions for the design of concrete, steel and composite structures and also with a few improvements for a day-to-day practice.


For more information read separate Technical Articles dedicated to individual improvements and extensions:

Steel-Concrete Composite Structures

  • Steel sheeting assigned to a composite slab is taken into account when running SCIA Engineer's steel design module.
  • Diaphragms contribute to the overall load-bearing capacity.
  • Catalogues for decking from European, British and North American manufacturers are integrated in the software.
  • Support of trapezoidal profiles with a re-entrant stiffener resulting in modified moment capacity of the composite beam in the case when the stiffener protrudes above the plane of the top flange.
  • Parasitic bending moments at the ends of, e.g., simple beams are avoided.
  • All loads are first transferred to the secondary beams, which in turn transfer load to the primary beams as concentrated forces.
  • Stiffness in the weakened direction of the slab is compensated by increased stiffness of the beams in order to obtain a realistic behaviour of the floor as a whole.
  • Lateral-torsional buckling checks are now performed also according to EN 1994-1 (previously only according to AISC 360).
  • Comprehensive fire safety verification is performed according to EN 1993-1-2/EN 1994-1-2 for both construction and final (exploitation) stages.
  • The simplified approach for limitation of crack widths in composite slabs is applied as described in EN 1994-1-1, §7.4. 2 and §7.4. 3.

Steel Connections

  • An additional output type is now provided alongside the brief and detailed reports - the summary output.
  • The "20% rule" is supported in the verification of the component Beam flange and web in compression for moment-stiff connections.
  • The output for splice connections now clearly describes the bolt-row classification and the calculated effective lengths of T-stubs.
  • The optimisation of internal algorithms resulted in speed gains.
  • Occasional issues in the visualisation of connections between members with a rotated local coordinate system have been cleared out.
  • The design of moment-stiff end-plate connection with four bolts per row is now supported.

Reinforced Concrete Structures

  • It is now possible to design ribbed slabs and also perform the required code-checks. There are no limitations concerning the shape of the rib cross-section.
  • An X-shaped cross-section has been added to the reinforcement templates.
  • A new approach to the calculation of 1D member deflections is based on the search for a minimal beam stiffness. It can be used in all situations, including the configuration with zero internal forces but non-zero deflections.

Table Results

  • A new "Red X" mark indicates in the model the location of the place examined in the Table Results.
  • Table Results are (optionally) automatically refreshed after Refresh in the Property Window.
  • The Property Window (with displayed results) now provides for a direct access to Table Result.
  • No longer required Table Results can be easily removed from the project to reduce the project size.

Automatic Mesh Refinement

  • The automatic mesh refinement is now performed on a group of user-selected load cases.
  • In the Results service both the error estimation and proposed refinement for each element can be displayed.

GUI improvements

  • Filter is now available not only in Project Libraries, but also in the System Libraries (e.g. library of manufactured profiled sheeting).
  • Smileys at the top of the application window allow for a fast feedback.
  • The Project Data dialogue has been simplified.
