The subject of the study is to improve earthquake and wind response of slender structures by using Tuned Mass Damper (TMD) applications. TMD application on main structure reduces the structural response amplitude by creating additional damping. A vibration analysis employing transfer matrices was applied for a slender structure with varying cross sections. The analysis is applied to an existing reinforced concrete minaret structure as a case study due to its poor dynamic response and lack of sufficient studies. Best applicable and efficient TMD type was investigated to improve the dynamic response of selected minaret structure. Structure response was analyzed with and without TMD installation by using MATLAB for discrete mass model. Harmonic excitation was considered to simulate the ground motion and improvements in the response were discussed. SAP2000 software was also used to analyze the same structure through Finite Element Method technique. 1999 Kocaeli and 1999 Düzce earthquakes ground motion records were used to verify the effectiveness of the developed TMD. Wind response is also considered. Detailed fabrication drawings were prepared by considering the challenging installation constraints. Feasibility study of the developed TMD was discussed for applications either in new structures or retrofits.
