"Terma Bania" Building Extension and Renovation in Białka Tatrzańska, Poland
This project was designed using BIM technology. During the documentation process, IFC files were used for the data exchange. The architectural building model was first created in REVIT, then exported to RFEM to apply loads and complete the full structural analysis and design.
"Terma Bania" Aquapark
An additional extension, which includes lounge and restaurant areas, was added to the existing "Terma Bania" aquapark. The building was designed as a reinforced concrete monolithic slab-column structure. The underground supporting column spacing is 20 ft x 25 ft, while the aboveground spacing corresponds to the roof girder span. The building's lateral stiffness includes two stairwells and elevator shafts. The RFEM RF-CONCRETE add-on modules were used for the design of the reinforced concrete elements.
Due to the terrain conditions and the need to maintain the existing façade’s continuity, an arched roof was required. The goal of the design was also to minimize the number of supports at the ground and basement levels. Therefore, the roof structure is composed of glued laminated timber GL28h arch girders with two span lengths: 54 ft and 73 ft. The roof girders are pinned at their ends, supported by reinforced concrete beams. The RF-TIMBER Pro add-on module was used for the design of the glued laminated timber elements.
Due to the building’s display requirements, a glass façade was designed on the south side. Steel columns are used as the load-bearing elements. The roof structure in the glass façade plane is crowned with a reinforced concrete beam with two curvature vertical and horizontal radii. The reinforced concrete beam was modeled as a series of single-segment beams. The RF-Concrete Members add-on module was then used to design the series as a set of members, whereas the façade’s steel columns were designed in the RF-STEEL Members add-on module.
Because the building is composed of multiple materials (steel, reinforced concrete, glued laminated timber), performing the analysis and design in a single software was possible utilizing the RFEM program and add-on modules. Modifications to the structure as well as the loads were possible in RFEM, significantly accelerating the design process.

This article compares the design to the one in the referenced article: Design of Concrete Columns Subjected to Axial Compression with RF-CONCRETE Members. It is, therefore, about taking exactly the same theoretical application carried out in RF-CONCRETE Members and reproducing it in RF-CONCRETE Columns. Thus, the objective is to compare the different input parameters and the results obtained by the two add-on modules for the design of column-like concrete members.
- I have a roof structure resting on a steel column that runs to the foundations. The column runs through a perimeter wall that supports the false ceiling. A considerable part of the load from the roof is transferred to the wall. I want the steel column to carry all the vertical loads from the roof. How can I do it?
- Are the models and presentations from Info Day 2018 freely available, and can you send them to me?
- In RF‑CONCRETE Surfaces, I obtain a high amount of reinforcement in relation to a lever arm that is almost zero. How is such a small lever arm of internal forces created?
- How does the "Orthotropic Plastic" material model work in RFEM?
- What is the meaning of the superposition according to the CQC rule in a dynamic analysis??
- When converting from the manual definition of reinforcement areas to the automatic arrangement of reinforcement according to Window 1.4, the result of the deformation calculation differs, although the basic reinforcement has not been modified. What is the reason for this change?
- Does the program check the lap length of the vertical stirrups of a block foundation with smooth bucket sides?
- Why do I get a discontinuous area in the distribution of internal forces? In the area of the supported line, the shear force VEd shows a jump, which does not seems to be plausible.
- Is there a possibility in RFEM to define a global polar grid with the origin lies in the global zero point, for example, and which applies to several surfaces?
- When comparing RF‑CONCRETE Columns with another design software, I get different results. How to explain the differences?
