Concrete Slab Roof of Underground Parking Garage

The bachelor thesis deals with the roofing of an underground parking garage with reinforced concrete slab with point supports. The objective of the thesis is to find out the internal forces on reinforced concrete slab in two construction variants, as well as the analysis and design of one of the construction variant. The replacement frame method and Finite Element Method were used for calculation of internal forces using a 2D model in the Dlubal RFEM 5.17. The work also includes the design and check of one column.

The structure of the roof was designed in two variants.

The first variant is a plate with the constant thickness, and the second one is a plate with reinforcing slabs in the area of columns. The second variant was subjected to the ultimate limit state design and the serviceability limit state design. The values from the plate model from RFEM 5.17 were used for the design.

The aim was to compare the internal force values obtained from both calculation models and the comparison of both construction variants. Furthermore, the design and analysis of an inner column was performed. The results include the relevant drawing documentation.

Knowledge Base Articles

RFEM Model with Permanent and Variable Loads

This article deals with rectilinear elements of which the cross-section is subjected to axial compressive force. The purpose of this article is to show how very many parameters defined in the Eurocodes for concrete column calculation are considered in the RFEM structural analysis software.

RF-CONCRETE Members also includes the design of a shear joint. In order to perform this design, you should select the "Shear joint available" check box in Window 1.6, Shear Joint tab.

Adjusting Reinforcement Directly in Graphic Window

It is possible to edit a reinforcement layout or an existing reinforcement directly in the reinforcement's 3D rendering.

Fire Resistance Design with CONCRETE and RF-CONCRETE Members

The reinforced concrete design for fire situations is carried out according to the simplified method based on EN 1992-1-2, Clause 4.2. The "zone method" described in Annex B.2 is used: The cross-section is subdivided into a number of parallel zones of equal thickness, and their temperature-dependent compressive strength is determined. The reduced load-bearing capacity in the event of fire exposure is thus represented by a reduced structural component's cross-section with reduced strengths.

Product Features

Transfer of Reinforcement from RFEM/RSTAB (Top) to Revit (Bottom)

The reinforcement proposal from RF-/CONCRETE Members can be exported to Revit. The rectangular and circular cross-sections are currently supported.

The reinforcement bars can be modified retroactively in Revit.

Transfer of Reinforcement Objects from RFEM to Revit

Surface reinforcements defined in the RF-CONCRETE Surfaces add-on module can be exported to Revit as reinforcement objects via the direct interface. To do this, you can optionally select surface, rectangular, polygon, and circular reinforcement areas in RF-CONCRETE Surfaces. In addition to bar reinforcement, it is possible to export mesh reinforcement.

Feature 002801 | Punching Shear Design for All Section Shapes

Do you have individual column sections and angled wall geometries, and need punching shear design for them?

No problem. In RFEM 6, you can perform punching shear design not only for rectangular and circular sections, but for any cross-section shape.

Feature 002691 | Simplified Fire Resistance Design for Columns and Beams According to EN 1992-1-2, Sections 5.3.2 and 5.6

The Concrete Design add-on provides you with the option to perform the simplified fire resistance design according to EN 1992‑1‑2 for columns (Section 5.3.2) and beams (Section 5.6).

The following design checks are available for the simplified fire resistance design:

Columns: Minimum cross-sectional dimensions for rectangular and circular sections according to Table 5.2a as well as Equation 5.7 for calculating time of fire exposure
Beams: Minimum dimensions and center distances according to Table 5.5 and Table 5.6

You can determine the internal forces for the fire resistance design according to two methods.

1 Here, the internal forces of the accidental design situation are included directly into the design.
2 The internal forces of the design at normal temperature are reduced by the factor Eta,fi (ηfi), then used in the fire resistance design.

Furthermore, it is possible to modify the axis distance according to Eq. 5.5.

Frequently Asked Questions (FAQ)

What is the maximum number of reinforcement groups that can be created in a design case in RF‑CONCRETE Surfaces?

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?

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?

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 seem plausible.

Is it possible to perform design without an additional reinforcement in RF‑CONCRETE Surfaces?

I obtain different results when comparing the deformation analysis in the RF‑CONCRETE add-on modules and another calculation program. What could be the reason for this?
