Concrete design improvements in version 18

 

18.0

 

Version 18 of SCIA Engineer brings a new improvement regarding the design of 1D and 2D members.

The idea of this improvement is to speed up the workflow of the design and to make a further step in the direction of a one-click solution. Moreover, some other improvement in this version is related to fix some bugs from the previous release and to speed up the calculation time and to give more stability to our designing tool.

Highlights

Speed up the design of 1D and 2D by introducing a new design default templates

Extend the pre-fabricated reinforcement mesh (welded wire mesh)

Extend the check for torsion with 9.2.3(4) requirement form EN 1992-1-1 code
Bug fixing (solve the problem of “Not all members have been checked”)
Improve the speed of the calculation and memory consumption

New design default setting

In this version of SCIA Engineer, new default values have been introduced to speed up the workflow of the design of 1D and 2D members. In the previous version of SCIA Engineer, when the concrete design clicks on As prov., the results were empty unless, the user define the necessary data as basic and additional reinforcement which was consume some time from the user.

This version has solved this issue and the user will not need to define the basic and additional reinforcement in the design default. The new default values have been decided based on the most used cases and the user still has the possibility to modify the content or to select another template from the design default to meet the requirement of the design for his project.

Extend the library of pre-fabricated reinforcement mesh for concrete 2D design

The prefabricated mesh of steel reinforcement (welded wire) is quietly used by the concrete designers. This type of reinforcement can be used with the solution form SCIA Engineer. In this release, the library of this type of reinforcement has been extended and updated to meet the needs from the market.

Below in the table, you can see the new supported types:

Country Supported mesh type
Standard mesh The Netherlands

Type P Mesh

Type PS Mesh

Type BEC Mesh

Standard mesh Belgium

Type P Mesh

Type PS Mesh

Type B Mesh

Standard mesh Germany

Type Q mesh

Type R mesh

Standard mesh France Type CAF, TS, TS50 and TS60/65 mesh
Standard mesh the United Kingdom

Type A, AM, AFE and AEC mesh

Type B mesh

Standard mesh Norway Type K mesh
Standard mesh Sweden Type SE mesh
Standard mesh Denemarken DK mesh

Extend the check for torsion with 9.2.3(4) requirement form EN 1992-1-1 code

According to this requirement, the longitudinal bars for torsion should be so arranged that there is at least one bar at each corner, the others being distributed uniformly around the inner periphery of the links, with a spacing not greater than 350 mm. This check was handled in a good way for the design only in the previous releases. Therefore, version 18 of SCIA Engineer has solved this issue and now the concrete designer can see that if this check is active, the calculation will respect this check by putting the min four corner bars and by checking the 350 mm distance.

Bug fixing (solve the problem of “Not all members have been checked”) and speed/memory improvement

It might be that you faced an error message when you tried to calculate the reinforcement for 1D or 2D elements in version 17. This error message was saying "Not all members been checked". This issue was recognized by our quality team and by some of our clients.

Version 18 of SCIA Engineer includes the necessary fixing for this issue. This issue was happening due to some Windows protection requirements and in some other cases due to the memory consumption of the project. Therefore, the new implementation has solved that bug and at the same time, improve the memory consumption for the concrete design.

As you can see from the test below, for a multi-story building which contains around 1000 1D and 2D elements, the calculation was smooth and the time of the calculation was quite fast.

Description Number of elements Time in seconds
2D elements design (in node ava) 1030 136
2D elements design (in node ava on macro) 1030 340
1D elements 924 400
