Winding staircase in exposed concrete - Franz Oberndorfer GmbH & Co KG

About the company
Oberndorfer is known to be a dynamically growing company with decades of expertise in producing, assembling and distributing precast-concrete products.
Their core competencies comprise:

• the most efficient manufacture of various precast-concrete products thereby employing the latest production technology;
• outstanding expert know-how in the fields of automation, building statics and technical engineering;
• operative know-how in the area of transportation, logistics, on-site assembly and distribution.

About the project
The project is about a winding staircase in exposed concrete at the 'Office Campus Gasometer'- building of Vienna, Austria. This emergency stairway sets a striking symbol on the clean lined façade of the building. Like a campanile, the eye-catching structure extends up to the sky.
With a diameter of 5.16m, a weight of about 150 tons and a height of more than 20m, this precast structure nevertheless appears slim, in front of the immense piece of real estate. In order to meet the quality requirements for the engineering design and the exposed concrete, utmost precision and a great deal of experience in precast construction were necessary. It was easy to realise the specified architecture in virtual components; the production and the changes in the configuration of the reinforcements were also easier to develop using 3D illustrations.

The most important parameters for this project were the massive formwork for obtaining a precise matching of the prefabricated units, high-performance concrete and finally an experienced team.
After the static design, 30/37/B2/GK16/F73 SCC was used. To withstand the enormous concrete pressure and upward-acting force of 5m³ SCC, the formwork had to be made of 10mm thick steel plates with many additional reinforcements. For every two prefabricated parts there is a footbridge of cast-in-place concrete leading to the corresponding floor (6 storeys in total).
Allplan Engineering and Allplan Precast were used for this project.

Scia Engineer Tips & Tricks: Creating high resolution pictures

There are different ways to create a picture from your Scia Engineer model (with our without results). The best known method is making a screen shot by means of the [Print Screen] button or a special tool for screen captures. But suppose that you want to use this picture for an important document, a presentation or any printed material. In that case, it is required to save the picture to a format with high resolution. You will find below some tips on how to create such clear and high resolution pictures from Scia Engineer models.

In Scia Engineer you go to the File menu > Print Picture > Save picture to File, see image 1.
Next, you get the choice between different types of graphical formats, see image 2.
Let's take the most frequently used graphical format: JPEG (*.jpg).
After inserting a file name, the following dialogue pops up, see image 3.

Image 1	Image 2	Image 3	Image 4

It is very important to choose a correct picture size here. You have the possibility to fill in the width; the recommended value is 3000 pixels for high resolution. The height is automatically adapted.

Note: it is possible to enter a value between 10 and 100000 pixels for the width. Bear in mind however that the larger the size is, the longer it will take to save the picture.

It is also possible to adapt the JPEG quality. This can be preset to 100% for good quality pictures.
Furthermore, it is possible to (de)activate the isoline palette and the coordinate axes, if they appear in the drawing.

The difference in quality is clear if we take a look at image 4: Screen capture (*.jpg) Save picture to file (*.jpg).
