SCIA Engineer 16 Beta programme
To give users of SCIA Engineer the opportunity to participate in the development of SCIA Engineer, SCIA Engineer version 16 includes a Beta version for SCIA Engineer users and tester.
All SCIA Engineer users are invited to participate in the testing of our Beta version of the design of 2D concrete members according to ULS and some other enhancements in the design of steel members.
To apply for Beta version please click on the following link beta.scia-engineer.com.
What the user can test in the Beta version of SCIA Engineer?
- Calculation of the statical reinforcement of 2D members (walls and floors).
- Calculation of shear reinforcement in 2D members.
- Application of "shift rule" based on EN 1992-1-1.
- Speed and performance of the reinforcements design of the 2D concrete members.
- The usability of "Table Results" in the verification of concrete members.
- New tools for section classification and calculation of effective section properties for steel design.
Design of 2D concrete members
Steel design enhancements in the beta module
A new tool for the classification of steel cross-sections will be made available in SCIA Engineer release 17.0. The functionality is already implemented and accessible as a beta module and users can test it.
What it is
The Classification Tool determines the cross-section class based not only on geometry, but also on the set of internal forces that are present in the particular section along the member. This means that during the verification of steel members, the Classification Tool will run and determine the section class per (1) section along the beam and per (2) load case/(sub-)combination the check is performed for.
The Classification Tool automates the classification of any cross-section shape that can be represented by a centreline. As a result, more economical designs are obtained for sections that could previously not be classified (and were thus deemed as class 3). Also in the case when certain sets of internal forces (N, My, and Mz) produce a lower section class, the use of the Classification Tool results in more economical unity checks values in the Steel Check.
The performed section classification is fully in accordance with Table 5.2 of EN 1993-1-1.
A choice between three methods
Three methods are available for the determination of stress distribution inside the cross-section when bending is also present in the member:
- the user may derive the plastic neutral axis based on the elastic stress distribution, or
- he/she may use two of the other more accurate full plastic approaches, namely, an iterative procedure that gradually scales the set of internal forces, or a method based on a pre-calculated yielding surface (in N-My-Mz space) for the cross-section in question.
Various computational routines are implemented in order to provide a fast calculation also in the case when the user would like to use the more accurate techniques for determination of the plastic neutral axis.
Plastic stress distribution in the section is based on an elastic-perfectly-plastic stress-strain diagram.
Output and standalone tool
The Classification Tool is now available directly from the Cross-section Properties (our Beta module is required).
The tool provides a clear overview of the size and stress in the different section parts and the intermediate calculation steps during the classification.
It is also possible to check the section class for a set of manually inserted internal forces (in order to e.g., assist the user with hand calculations).
Effective section tool
Previously available for cold-formed steel sections only, the calculation of effective section properties will be made available in release 17.0 of SCIA Engineer for members that fall under the EN 1993-1-1 standard. An effective cross-section can now be calculated for any shape that can be represented by a centreline:
- welded and hot-rolled steel profiles of various shape,
- user-defined cross-section shapes (e.g., free-form thin-walled shapes),
- combinations of steel profiles welded together, etc.
What it is
The Effective Section Tool:
- recognizes the internal and outstand walls of the steel shape, the corners and folds that may be considered as (intermediate/edge) stiffeners;
- calculates any potential reductions due to localised buckling in the member both under compression and under bending;
- uses the effective section for the corresponding section and stability checks required by the EN 1993 code.
Flat elements are taken into account with correct width during the calculation of effective section properties: for example, weld sizes will be taken into account in the case of welded I-shapes, roundings will be taken into account in the case of hot-rolled sections or box profiles, gross dimensions will be used in the case of angle profiles.
Where to find it
The Effective Section Tool is now available directly from the Cross-section Properties (our Beta module is required).
It is also possible to view the effective section (and intermediate calculation steps to obtain it) for a user-specified load effect (stong-/weak-axis bending or compression).
Beta users of SCIA Engineer can now try a preliminary release of a link to Westok's Cellbeam software.
Cellbeam is a tool for the design of steel and composite cellular beams. The link allows you to design Westok beams with web openings after FE analysis: data from the SCIA Engineer model are transferred to the Cellbeam tool with a single click (cross-sections, support conditions, loads on the member, lateral restraints, etc.) and the optimised beams can be imported back and updated within the original SCIA Engineer model.
