Steel in low-rise building
A symbiosis of cold formed sections and light rolled profiles
This demonstration project aims to demonstrate that an intelligent combination of steel components covering hot rolled profiles, cold formed sections, tubular sections and flat products, leads to economical structures, thanks to a symbiosis between cold formed and hot rolled steel products. It consists in 3 demonstration buildings: Project I, named “CRM4”, is an intensive steel two levels office building which has been designed and erected during the research period. Important issues like structural, thermal, environmental as well as cost analysis are developed. This architectural building has... been achieved within a construction cost of 980 €/m2 and has been designed for efficient energy consumption leading to low use costs; Project II, named “Jeanne de Champagne”, is an existing social housing building with steel structure: In the scope of the report, the steel structure has been optimised and steel use possibilities have been investigated for the façade (thermal and environmental assessments); Project III, named “Cultural center” demonstrates the benefits of semi-rigid connections and composite design in low-rise buildings through economical comparison. These assessments on structural, thermal, environmental and economical aspects have highlighted that steel is a suitable material for low-rise buildings. The dissemination tools issued from the project are: steel solutions for low-rise buildings within Europe; a promotional video of 15 minutes, available in English and French language recorded on DVD support, explains in a very pleasant way each step of the CRM4 construction.
