Life Cycle Status
Operational since 1901
Mission and objective
The European Laboratory for Structural Assessment (ELSA) Reaction Wall consists of a reinforced concrete vertical wall and a horizontal floor rigidly connected together to test the vulnerability of buildings to earthquakes and other hazards. It is the largest facility of its kind in Europe and one of the largest in the world. ELSA Reaction Wall is a world renowned reference for experimental research and standardisation on the security, safety and stability of physical infrastructures and their critical elements. The facility was established in 1992. It is owned and operated by the Joint Research Centre of the European Commission. ELSA Reaction Wall has established formal agreements with the Korea Construction Engineering Development Collaboratory Management Institute (KOCED CMI), Building Research Institute in Japan, Tongji University (CN), Purdue University (US) and Cyprus University of Technology, and cooperates with all European research infrastructures in earthquake engineering. The RI provides Transnational Access through the SERA project and the Open Access to JRC research infrastructures.
