| Summary: | The purpose of this research is to investigate the effect of Recycle Tire Isolator
(RTI) as earthquake resistance system for low rise buildings in Malaysia. Most
of the earthquake’s victims are due to the collapse of poorly designed concrete
and masonry buildings. Therefore, an economical but reliable RTI is introduced
to solve the problem in most of the developing countries such as Malaysia. This
study focuses on the effect of RTI-5 (5 layers RTI) in protecting three stories
buildings. The vertical displacement of RTI-5 was determined through static
compression test. The maximum vertical displacement of RTI-5 was obtained
when the specimen was monotonically loaded to failure. Finite element analysis
was carried out by using ANSYS V16.0 to model the RTI-5 and the results
obtained were compared to the experimental results. The dynamic stiffness and
damping ratio of RTI-5 were investigated through dynamic test. The behaviour
of various thickness of RTI were examined and compared with Rubber Bearing
(RB) and Scrap Tire Rubber Pad (STRP).Total displacement of three stories
buildings on fixed base and on base isolation were determined. The results from
static compression test and finite element analysis showed that RTI-5 could
sustain a vertical load of 380 kN with vertical deformation of 12.5 mm. It has
been verified by finite element analysis (FEA) where both of the results
achieved close agreement in terms of vertical deformation. RTI-5 and STRP
have similar vertical stiffness due to the employment of same material in
fabrication. However, rubber bearing is stiffer than RTI-5 due to the present of
embedded steel plates. Besides, RTI-4 is stiffer than RTI-5 due to the number of
layers are lesser in RTI-4. The results of dynamic test shown that RTI-5 has
higher damping ratio than RTI-4. In overall, total deformation at the top floor of
the three stories building is reduced by 83% via implementation of RTI in the base of the building. It has been proven that RTI can reduce the total
displacement of low rise building effectively |
