The behavior of rubber perforated woven roving fiber glass (RPWR) as a base isolator composite material

Abstract

Buildings suffer structural damage as a result of natural disasters, particularly earthquakes. Adding technology, such as a base isolator at the building's base, can help to mitigate such damage. In this study, a three-story reinforced concrete structure with eight columns employed the base isolator RPWR with end and top plates, rubber hardness 70, 80, 90, and woven fiber roving type 4 composed the RPWR. The hole pattern on the fibers in the RPWR layer allows the rubber to adhere to each other and improve stiffness. We were investigating RPWR using the Finite element method. From the test results, the three samples produced a minimal damping ratio value. However, compared to previous studies that used fine wire mesh, the use of woven roving type 4 was ineffective. Therefore, it proves that using fiber woven roving type 4 still needs to be considered in another way.
