Abstract

Current trend in construction industry demands taller and lighter structures, which are also more flexible and having quite low damping value. These structures are flexible and constructed as light as possible, which have low value of damping. This increases failure possibilities and also problems from serviceability point of view. Current trends use several techniques to reduce wind and earthquake induced structural vibration, out of the several techniques available for vibration control, concept of using TMD (Tuned mass damper) is a newer one. This study was made to study the effectiveness of using TMD for controlling vibration of structure. Passive tuned mass damper (TMD) is widely used to control structural vibration under wind load but its effectiveness to reduce earthquake induced vibration is an emerging technique. Total two types of models, i.e., 3D frame with single TMD and 3D frame with double TMD are considered. Total six numbers of loading conditions are considered named sinusoidal ground acceleration, EW component of 1940 El-Centro earthquake (PGA=0.2144g), compatible time history as per spectra of IS-1893 (Part -1):2002 for 5% damping at rocky soil (PGA=1.0g), Sakaria earthquake (PGA=1.238g), The Landers earthquake (1992) (PGA=1.029g) and Mexico earthquake(1995)(PGA=1.24g) for time history analysis of considered model. The effectiveness of single TMD to reduce frame vibration is studied for variation of mass ratio of TMD to 3D frame. Also the effect of double tuned mass damper on the 3D frame response is studied for variation of mass ratio of damper. From the study it is found that effectiveness of TMD increases with increase in mass ratio. Use of double TMD is much more effective than single TMD of same mass ratio for vibration mitigation under earthquake as well as sinusoidal acceleration.
