Finite Element Analysis of Kevlar Reinforced Rubber as Seismic Isolator
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
The seismic isolators are one of the modern innovative solution for building protection against the seismic behaviour of earth. Using the scope of composite materials we can create better solution for engineering problems arises due to earthquakes. Nowadays, an innovative material Kevlar is used as seismic isolator. Finite element simulations were carried out using ANSYS15 for the mechanical characterization of multi-layer elastomeric isolation bearings. Conventional steel plates are replaced by the fiber reinforcement. Fiber reinforced elastomeric isolation bearings are low cost alternative to the conventional steel-reinforced bearings. Some experiments were conducted in the past to assess their effectiveness. The development of lightweight, low-cost isolator is crucial if this method of seismic protection is to be applied to a wide range of buildings such as residential, school and hospital buildings etc. in rural and urban earthquake-prone zones. The main aim of this study is to find the effect of a high strength composite material Kevlar reinforced rubber as a seismic isolator. For this, circular isolators of increasing depth ratio were modelled using ANSYS 15. Horizontal displacements were applied at different oscillations and the horizontal stiffness and damping ratios were calculated. The study reveals that damping of the structure decreases with increase in depth ratio.
