development of earthquake-resistant building types

using local available materials (traditional building types)

steel-frame constructions (project SEQD – Steel Earthquake Design)

Past experience has shown that steel is a favourable construction material for earthquake-resistant buildings. Nevertheless some unexpected damage cases have ocurred on steel structures due to seismic impacts, as for instance in Bam 2003.

Previously most steel structures have been designed for industrial buildings, bridges and high storey buildings; there are no solutions for small buildings applied on a significant scale. The SEQD -Steel Earthquake Design- project aims to provide a safe and economic solution for this sector.

At the beginning of October 2004 a new innovative steel system was tested in an assembly hall of the Rudolstädter Stahlbau GmbH. The first test line was dedicated to verifying the deformability of the system and the functionality of the uniaxial coupling. In the second test line the strength and deformability of the masonry and adobe walls, reinforced with two different polymer grids, was analysed.
