The 200 m high industrial stack made of reinforced concrete was built in 1974. The global maintenance state of the structure was analysed in the scope of a detailed, dynamic structural measurement with BRIMOS®. The records of the permanent measurement contained information on effective structural accelerations at two spots for the determination of the load bearing capacity as well as on the movement of two selected vertical cracks. The permanent annual condition monitoring with BRIMOS® was carried out with regard to appropriate maintenance measures and rehabilitation concepts.
