Abstract High and slender sightseeing towers are subjected not only to a wind caused vibrations but also to a human’s caused vibrations. If the natural frequency of the structure is close to the frequency of the human pacing, then human and structure’s interaction should be considered in the tower design. The main component of the sightseeing tower is stairs and human movement on them generates significant longitudinal and transverse force components that cause sightseeing tower’s torsional and transversal vibrations. Additionally there could be a resonant built up problem that causes increase of the service stress range. There were experimentally measured vibrations and obtained a real time history of the eccentric, 36 m high steel structure sightseeing tower in Jurmala, Latvia
