Laminated Rubber Bearings Analysis and Design for Structures in Seismic Regions

Abstract

For the earthquake protection systems, the seismic base isolation is most popular. Basically, Seismic base isolation isolating the structure and its contents from strong ground motion that reduces an earthquake effect. In building structures exclusive sorts of seismic isolation and passive systems were used commonly for solving problems related to the earthquake vibrations or wind loading.Using passive energy dissipation systems for seismic design is a quite latest development, although there at the moment are examples of these systems at some stage in the arena. On this observe, the authors tried to demonstrate approval application of LabVIEW (Laboratory Virtual Instrumentation Engineering Workbench) program in designing the structural bearings and also its potential to giving correct responses using finite element analysis. The LabVIEW design has been demonstrated and validated with the prevailing literature. Finite element analysis the usage of ANSYS is executed, to examine the effect of lead core and shape of the bearings. Design of elastomeric bearings with lead is massive because the energy dissipation is high. From the outcomes, elastomeric bearing with lead shows higher mechanical properties and for this reason recommended for the strong seismic location.
