INVESTIGATION OF THE TUNED LIQUID WALL DAMPER CONTRIBUTION TO THE DYNAMIC PARAMETERS OF THE PRESTRESSED REINFORCED CONCRETE STRUCTURE USING FEM

The destructive effects of seismic loads on structures are known. Earthquake engineers have taken many precautions in their building designs to protect and minimize these destructive effects. In this way, many new design and reinforcement methods have been developed against seismic loads. The use of a tuned liquid wall damper (TLWD) is one of the developed methods. Therefore, in this study, the effects of TLWD on dynamic performance in a 6-storey prestressed reinforced concrete building model were investigated. For this, two models with and without TLWD were created by the finite element method and modal parameters were compared. As a result of the data obtained, it has been observed that the building model makes more balanced displacements, as can be understood from the mode shapes, without increasing the period of the building to a dangerous level. TLWD reduced the seismic effect by on the structure. It can be used in TLWD prestressed reinforced concrete structures
