Analysis of the Behavior of High-Rise Structures with Viscoelastic Dampers Installed at Various Locations
Abstract It is essential to analyze the behavior of each and every tall structure in the perspective of structural engineering when subjected to severe ground motion or earthquake. Vibratory forces are produced due to the result of such earthquakes at the base of the structure. Oscillations are created in buildings as a result of these vibrations. Such oscillations may cause severe damage to the structure. From the ground level, the vibrations get transmitted up to the top of the building and since the structural mass which creates lateral forces on the frame, the moment resisting capacity gets diminished for that of building components such as columns, beams, etc. This paper gives an idea of the different research works executed on a multi-storey building frame by taking various parameters into account. It explains the results of a study on the seismic behavior of a tall structure (G+15) installed with a damper. From a previously conducted experiment, it has been expressed that the stiffness and the strength of the structure enhances considerably with the use of such dampers. The current work aims to analyze the behavior of a multi-storeyed building for the most efficient location of viscoelastic damper in the structural system. A standard finite element software is used to carry out the analysis. Various parameters like lateral storey drift, base shear, time period, modal shapes, etc., are being analyzed and evaluated for the damper being placed at different locations.
