It has been used in a survey carried out in Istanbul about fundamental frequency assessment of 103 tall buildings. The records obtained are analyzed, and a fundamental frequency – building height relationship for tall reinforced concrete buildings in Turkey is proposed. Furthermore, the laser vibrometer has been used in a survey for the assessment of fundamental frequencies of damaged and undamaged buildings in İzmir following the 30.10.2020 Samos-Sığacık earthquake. The records taken from 38 buildings are analyzed, and characteristics of fundamental frequencies of buildings in different damage states are discussed.30 cm.Vibration -- Mathematical models.Vibration -- Data processing.xi, 55 leaves ;
