Technical Characteristics of Light Steel Houses
Technical Characteristics of Light Steel Houses
- General Introduction to the System
Our products are made using materials that meet EURO 1 certification standards.
2.Manufacturing Technology:
In the structural support system, materials conforming to DIN EN 10326 are utilized, including S320GD+Z, +AZ Erdemir (quality no. 1332), S350GD+Z, +AZ Erdemir (quality no. 1335), and/or Erdemir (quality no. 1322). We use thin-walled galvanized C- and U-profiles, which are produced as a single piece on fully automated continuous molding machines controlled by Cad-Cam systems. These profiles, available in thicknesses of 0.8 mm, 0.9 mm, 1 mm, 1.2 mm, and 1.4 mm, are designed according to static calculations that consider regional and climatic conditions.
Assembly
Wall panels, roof trusses, purlins, and intermediate floors are installed using specialized screws and bolts.
Static Calculations
Under Turkish standards and/or international standards specified in Article 3, the necessary seismic and static calculations are performed based on the suitability of the building for its intended use and its geographical location. These calculations are conducted using software such as SAP2000, CFS, STA4CAD, BRICSCAD, and HAYESCAD, following the load values defined in the project and relevant standards.
Solidity / Reliability
The external Coating comprises Bordeaux or Betopan, both of which are CE-certified for fire and water resistance. The internal lining is made from 8 mm thick recycled material, consisting of 65% polyethylene, 20% paper, and 15% aluminum board (OSB), along with 11 mm thick plasterboard.
Foundation Concrete
Concrete must be poured according to the concreting plan (foundation dimensions) provided by SERA MEKANİK. The design, statics, foundation, and flooring will be carried out by the customer. The building is anchored to the concrete base using steel dowels. For hardened soil, a foundation should be prepared using anchor slabs or a steel mesh foundation.
3.Technical Data
Roof Load:
148 kg/m², TS 498 (depends on snow load and the height of the building)
Wind Speed:
102 km/h (50 kg/m²) TS 498
Average Load per Floor:
According to TУ 498, it can be 200/350/500 kg/m² depending on the building’s purpose and type of use.
Earthquake Calculations:
Effective soil acceleration coefficient: Ao=0.45 (1st degree earthquake zone)
Building importance factor: I=1
Active load participation coefficient: n=0.3
Calculated as I=1/1.2/1.4/1.5n=0.3/0.6 depending on the purpose and type of use of the building.
