Investigation on sand-tyre mix base isolation system subjected to static loading

Investigation on sand-tyre mix base isolation system subjected to static loading The earthquake-related destructions in buildings are alleviated by uncomplicated methods with the implementation of the sand-tire mix as the base isolation material below the footing in which the tyre scraps are widely available from used automobile tyres.

Abstract

The earthquake-related destructions in buildings are alleviated by uncomplicated methods with the implementation of the sand-tire mix as the base isolation material below the footing in which the tyre scraps are widely available from used automobile tyres. The research is a preliminary investigation of the geo-base isolation system (sand-tyre mix) to be used for seismic ground vibration. Rubber, the primary raw material for elastomeric bearings, will be replaced with a sand-rubber mix. This paper clearly applies straight-forward experimental method of the application of static loading on a selected model footing in different trials for the study. The behavior of the footing is studied for different combinations of Crumb rubber (CR), such as 0, 10, 20, 30, and 50% crumb rubber (CR). From the investigation it is concluded that 30% CR and 50% CR combinations have significant load carrying capacity compared to other combinations. Moreover, with 30% CR and 50% CR combinations, the footing is able to resist punching failure at greater loads significantly. Additionally, the practical reality and literal facts for the implementation of this type of isolation system are discussed, where future researchers find a way to solve the potential drawbacks in these methods, apply them to real-life structures and buildings and shall be a better seismic shock absorber.
