Abstract

Now a days, in densely populated areas it is desired to have a taller structures which are light in weight and also very flexible. But in real cases the weight is higher thus they are more vulnerable to the environmental load and may lead to collapse of the structure and generate the serviceability problems. Different types of approaches are available to minimize the response of the structure, from the different approaches concept of Tuned Liquid Damper (TLD) is a newer one to reduce the response of the structure. In the TLD, liquid is filled in the tank which reduces the response of the structure using action of liquid sloshing. These TLD dampers are economical as well as less serviceability cost effective passive response reducers, which are being used in the structure having less stiffness and having a low value of damping of structure. In this study, considering Tuned mass damper (TMD) analogy the response of the Single Degree of Freedom (SDOF) system with nonlinear behavior of Tuned sloshing water damper (TSWD was investigated. Four different earthquake ground motion time history like Imperial valley (1940), Loma prieta (1989), Northridge (1995), Kobe (1994) has been used to investigate the behavior of SDOF structure with water sloshing damper. A numerical study was carried out with different important parameters such as mass ratio, and frequency ratio the results showed that there was a reduction in the acceleration response of the structure up to 33% by using different mass ratio. It is also observed that 4% mass ratio is most effective for the acceleration response reduction of the structure.
