A STUDY ON RESPONSE REDUCTION FACTOR OF R.C. STRUCTURE CONSIDERING VISCOUS DAMPERS

Abstract

The main importance of a frame as well as flat slab building is its serviceability and stability with time after sustaining all the natural calamities occurred in their life span. Viscous damper are energy dissipating devices which act as shock absorbers. During seismic events, the devices become active and the seismic input energy is used to heat the fluid and is then dissipated. Apart from installation, the dampers are low cost maintenance. They have been shown better stability and dependable properties for seismic designs.
Nonlinear viscous dampers for different frame as well as flat slab buildings are designed with the help of certain equations and after that are “oriented in two different locations of the buildings one is the periphery of the structure and the second is the central core of the structure and the comparison is carried out for the orientation of the viscous dampers and its effect on response modification factor of the structure. Prime Objective of work is” to generate Response Reduction Factor for RC Frame Buildings and RC Flat-Slab Buildings with and without Viscous dampers with different damping percentages that are 3%, 6%, 9%, 12% & 15% addition to inherent damping i.e. 5%. “To Evaluate Seismic Performance of RC Frame Building & RC Flat-Slab Building with and without viscous dampers by
performing Nonlinear Static Pushover Analysis. Investigate the effect of different viscous damping on Response Reduction Factor for RC Frame and RC Flat slab structure. To Obtain the Response of Structure in form of Time Period, Mode Shapes, Storey Drift, Base Shear, Displacement, Roof Displacement, Performance Point and” Failure Mechanism.
