We present one of the projects for the Steel Lion Award, which won this year’s Pangolin Award. In this article you can read a detailed case study from the Tiszaliget Revitalization project.

Project general data

The main task of the structural engineers was to carry out the design of a support structure for a new slide track. This was prescribed by the architectural design to have slightly different slopes and curvatures than the existing ones which have been considered obsolete. The goal was to reuse as many of the existing columns as possible and to optimize the positioning of support placement, therefore minimizing the number of required cantilevers.

The design team handled the global structural calculations, as well as the joint calculations, detailing, and drafting. The main purpose even at the very beginning was to create a centralized parametric model in order to dynamically generate all the necessary model objects and communicate efficiently between the softwares. From the structural point of view, this meant the full model with complex geometry, loads, supports, etc. While from the detailing side a completed model with definitive joints.

The general workflow of the project

The versatile Grasshopper script

The script is capable to carry out the following tasks:

0. Input data processing

  1. Structural model parameter collecting
  2. Load definition according to the prescriptions (manufacturer, codes)
  3. Geometry creation via Grasshopper
  4. Tekla model generation
  5. Consteel model object generation
  6. Load assignment to Consteel beams

Input data processing

Two main input data were received: A 3D model of the assembled slide elements, and a geodetic survey of the existing structure. Both .dwg files were processed in Rhino 3D to prepare the centralized model which is directly linked to a Grasshopper script. The base model which contained the slide centrelines was distributed to separate layers and loaded into Grasshopper via the Elefront plugin, as well as the measured points of the existing columns. Using these points the centrelines of the columns were averaged.

Load evaluation

The slide manufacturers’ data sheet and the related load evaluation methods from the standard were imported to Grasshopper. This allowed us to calculate automatically the particular user, water, centrifugal, and snow loads for the given slide sections and to directly forward the results to the Pangolin plugin.

Automatically generated user and centrifugal forces with eccentricities

Producing the Consteel model

After a quick correction of the centrelines in Grasshopper, a preliminary Tekla model was created by the script in order to create rudimentary joint configurations using custom components and scatter through the model in every position. This model ensured that the correct eccentricities could be calculated in Consteel at the slide receiving joints due to the real centrelines of the supporting beams.

The generated model contained all the necessary model objects (e.g. all the beams with specific releases, load cases & combinations, etc.) to directly run and analyze the model from Grasshopper, which made it possible to check different support placements in a relatively short time.

The final model

After the structural verification and dimensioning process the verification of typified joint models (using IDEA StatiCa) for specific positions was also performed, e.g. for cantilever end node, bracing nodes, and slide receiving plates. The preliminary custom components were updated in Tekla Structures, thus creating the complete model which is ready to prepare the drawings was a matter of hours.

Conclusion

The parametric model was capable to generate multiple configurations and to assist throughout the whole project. The project’s total design duration was 2 months and was carried out by one structural engineer and one detailer. The script development lasted about 1 month and it is fully reusable for similar future projects.

In the future, the new Steel Lion Award will include all ConSteel-related competitions and contests – including the Hungarian User Day contest or Diploma Competition – to create a high-level, internationally recognized professional or graduate award for the Consteel user community. It is an initiative that celebrates and inspires structural engineer talents all over the world to compete with their best projects made in Consteel. In this article, we have put together a summary of how our incentive programs have evolved and how it supports the cultural sector at the same time.

Why have we created an international award?

The idea of creating a high-level international award for the Consteel user community has been ripe for a long time. Consteel software is a unique and advanced solution for designing steel structures helping engineers to create many excellent projects around the world every year. We would like to show these to the wider engineering community, so you can see how many creative implementations there are and how much the software can be used for.

In Hungary, we have already launched a smaller, domestic version of this award, in which our users have submitted many great projects and we have rewarded them every year on the Hungarian User Day contest. You can see previous winners here.

The first international Steel Lion Award

The Steel Lion Award is an initiative that celebrates and inspires structural engineer talents all over the world to compete with their best projects made in Consteel. As we are not only in the domestic market but also have a significant number of international users, we wanted to give them the opportunity to enter the competition with their work. Therefore, we launched the first international Steel Lion Award on 1 February 2022, which is not only open to Hungarian projects but now also looking for international ones. More information about the award can be found here.

The trophy was put out to competition among Hungarian artists and from the entries received we chose a young sculptor, Mihály Ágoston Gyurcsovics. Just as the lion is considered the king of the animals, with this The Steel Lion Award we are highlighting the best projects from the submitted models. In addition to the sculpture’s clean and elegant design, it was also important that the structure of the lion’s interior symbolized the steel structure design and valuable global connections that the ConSteel team has. The material of the award is stainless steel, which in addition to its structural functionality, is also excellent design material.

How to apply?

Currently, we have made it free for everyone to enter the competition, with a prerequisite that the company must have a live Consteel license. A company can apply for the award with more than one project, in which case an application form must be completed for each project. The size of the project or the size of the Consteel model is not a key factor during the evaluation, so the smaller projects with creative, unique solutions are warmly welcome. Applications will close on 16 March 2022 and will be reviewed by the professional jury.

The submitted projects will be evaluated by an international Consteel team of structural engineering professionals, academic professors. All the projects where the solution includes the use of scripting technologies (Pangolin or Descript) will be automatically evaluated for the Pangolin award. We believe that this new technology is the future of structural steel design, which is why we believe it is important to promote its uptake and spread within the profession. The winners will be announced during the International Consteel Meetup on 24 March 2022. More information about the event will be coming soon.

Apply for submission

What happens with the Diploma Competition?

The launched Steel Lion Award will include all ConSteel-related competitions and contests. This means that the domestic competition will no longer be organized separately, but instead, projects will be assessed globally, and the Diploma Competition, which was announced in previous years, will be merged into it. In 2023, the next competition for civil engineering graduates will be launched under The Steel Lion Award umbrella. This will be a change of name, of course, and the diploma will not be evaluated together with the projects submitted by experienced professionals.

As we have received theses from surrounding countries this year, which we consider to be a great step forward and see it as a good idea to expand this to an international competition, so that in the future young people from abroad will also have the opportunity to participate.
