Dynamic Seismic Spectrum Analyses of a 120 m High Reinforced Concrete Chimney According to Turkish Building Earthquake Code 2018 (TBEC-2018)

Reinforced concrete chimneys are tall and slender structures that are more vulnerable to seismic actions. In recent earthquakes, many of them severely damaged or totally collapsed. Therefore, it is an inevitable duty to analyze the structural response of these tall and slender structures under different seismic codes. In this study, the structural response of a 120 m high RC chimney under the seismic spectrum provided in Turkish Building Earthquake Code 2018 is determined. At the end of the analyses, the top displacement and base shear is obtained and the top displacement is compared with the limit value provided in ACI 307/98 that this comparison showed that the considered chimney is safe (only on the basis of top displacement comparison). Also, other linear and nonlinear seismic analyses should be performed to verify the structural response results obtained in this study.
