Plant engineering is characterized by continuously changing conditions due to modifications of the production processes. In the case of reconstructions, a reassessment of the construction might be necessary taking into account the modified static system of the structure. This represents a major challenge, especially in the question of earthquake safety.
SDA-engineering GmbH has many years of experience in the assessment of plants and the estimation of their earthquake safety. SDA-engineering was involved in the compilation of the VCI-Guideline, in which special rules regarding the consideration of earthquake loads in plant engineering are provided. An evaluation procedure for the assessment of earthquake safety of the structural system with respect to the interaction of the plant components and the load-bearing structure was developed and continuously improved in close cooperation with plant engineers.
Within the context of a transfer project, financed by the German Science foundation, new approaches for the assessment of the seismic vulnerability of existing plants were compiled by SDA-engineering GmbH in cooperation with RWTH Aachen University and the Chemical Industry. This knowledge was integrated into the further development of the seismic safety evaluation procedure of the VCI-guideline.
