Structural dynamics and earthquake engineering are core competences of SDA-engineering GmbH. The range of applications covers the dynamic analysis of structures and buildings in civil engineering, plant construction and mechanical engineering. The analyses are performed for dynamic actions due to earthquakes, explosions, impact, vibrations and vibration effects of all kinds due to internal or external sources. The results of the analyses are used to derive necessary measures such as retrofitting, vibration isolation or the installation of effective dampers. SDA supports the entire process and also offers the constructive implementation and execution planning of necessary measures.
