Investigation on the dynamic behavior of tower structures by theoretical and experimental methods

İskenderun Iron and Steel Factory is one of the oldest iron and steel factory in The Town of İskenderun of Hatay, Turkey. The dynamic behavior of tower structures such as Blast Furnace Stove Chimney, Rolling Mill Chimney, Water Towers and Flare Tower in İSDEMİR was examined in this study. Structural analysis program results were compared with the actual behavior of tall structures which were built according to different codes. It's aimed to fill the gap in the literature for this specific building types. Ambient vibration test which is the one of the structural monitoring system is used for determining the existing dynamic behavior of structure. Ambient vibrations are recorded on computer by the help of accelerometers. Dynamic characteristic behavior of the structure were analyzed with structural analysis programs and the results were compared with the behavior of the existing structure. Model calibration has been done with available data.
