Automatic design of reinforcement in 1D members




As usual, the new version of SCIA Engineer includes some development regarding the concrete design.

In this version (v19), the user can see that the main effort has been spent to improve the design capability of the 1D and 2D members.

Thanks to this new version of SCIA Engineer, the concrete designer can save a significant time since the new version solve most of the practicality requirements, for instance, having a constant amount of reinforcement for columns, correction of longitudinal bars for beams and ribs, and design of shear reinforcement based on practical distribution, etc.).

Introduce a new provided shear reinforcement (Aswm, prov.) for beams, columns, and ribs with practical zone distribution.
Improve the provided reinforcement solution by taken into account most of the practice requirement.
Introduce new template for column design (design with four corner bars, design with uniaxial or biaxial).
Improve the template of provided reinforcement for ribs (T and L cross-sections).
Possibility to select a list of diameter for designing any 1D members.
Possibility to select a specific diameter for detailing bars requirement.
Convert all the designed provided reinforcement (As, prov.) & (Aswm,prov.) automatically in one click to real bars.
Possibility to use the converted bars in all ULS/SLS checks and section check.
Possibility to edit the converted reinforcement after the design.
Possibility to export the converted reinforcement to IFC & XML.

Introduction of the new provided shear reinforcement for 1D members:

In the previous version of SCIA Engineer, the user was able to calculate the required shear reinforcement via two possibilities:

• Calculate the required shear reinforcement as an area (Aswm, req.)

• Convert the area of shear reinforcement to stirrups and spacing (Aswm.req (⌀ /s)

In this version, the shear reinforcement design has been improved to help the concrete designer get practical results quickly and efficiently.

In this version, the user can select the shape of the stirrups from the pre-built list in the reinforcement template. This list supports three cross-sections for beams (rectangular, T shape and L shape section) and two cross-sections for columns ( rectangular and circular).

The influence of the stirrups on the longitudinal bars will be taken in to account automatically by means of detailing bars. Those detailing bars will be inserted automatically when it is required either if that due to the shape of the stirrups or due to some other detailing role requirements. Moreover, the user must decide in advance the required dia that may use for those detailing bars.

Practically, the user has a different option to decide the way how he wants to distribute the shear reinforcement along the span of each member. The following options are supported in this version:

• Non: the provided shear reinforcement (Aswm, prov.) will follow the logic of Aswm, req. So there is no practical distribution.

• Based on Geometry: the span of each member can be divided into three zones as maximum and in each zone, one critical spacing will be used.

• Based on most recurring spacing: the software will calculate the length of each zone per spacing and based on an economical design the decision will be made. This option can give very practical distribution in many cases.

All this practical distribution is linked to the decision of the user regarding the max allowable zones. For example, in some cases, the user would like to apply uniform distribution along the whole span of the member. This case also can be done easily with this version where the user can select one zone only for that member and then the stirrups will be equally distributed along the span of the member based on the most critical spacing.

In addition, whenever the user wants to make symmetry from the left and the right of the span, s/he can activate the option to force asymmetrical spacing distribution.

Improvement of the column design:

In this version (v19), the column design has been improved to meet the requirement of having very practical results in few clicks.

One of these important improvements is the design with four corner bars. The idea from this improvement is to help the concrete designer for some cases where he wants to design only with four corner bars. This option can be selected via the provided reinforcement template.

This option can be used with the option of a list of diameter for the longitudinal bars where the user can select the four corner bars of the section and the software will find the best economical diameter to fulfill the requirement of the design.

Moreover, there are some other improvements have been implemented in this version like:

Uniformity of the longitudinal reinforcement along the length of the column. With this new feature, the user can see that SCIA EN will take the max required reinforcement and apply it over the full length of the column. Still, the user can see the actual reinforcement as As req. where the calculation determines the reinforcement in each section of the column.

Improvement of the beams and ribs design:

Uniformity of the reinforcement above the support: with this option the user can force the results to be uniform above the support. This option is working currently only working with continuous beams.

Minimum length of the longitudinal bars: with this option, the user can force the software to extend the length of the bars to meet the minimum selected length. This option is important to have practical results.

Automatic conversion of reinforcement to 3D bars:

The good news of this new version of SCIA Engineer is the automatic reinforcement conversion after the design. In the previous versions of SCIA Engineer, the users have always to spent a significant amount of time to remodel the designed reinforcement to real bars in order to be able to check this reinforcement for ULS/SLS checks.

Thanks to the new function of a convert to real bars, the user now in one click and instantly can convert the designed provided reinforcement to real bars.

The converted new reinforcement can be used in all ULS/SLS check and section check as well. Moreover, the converted reinforcement can be exported to IFC or XML.
