Technical Note: CONTACT ANALYSIS OF BASE ISOLATED MASONRY BUILDING

The concept of reducing the damaging effects on structure during earthquake by introducing some type of support that isolates structure from the shaking ground is a well-known method, named as base isolation technique. The isolation system reduces the effects of an earthquake by essentially isolating the superstructure and its contents from potentially damaging ground motion. In case of base isolated system the behavior of system mainly depends on type of base isolators and their contact with the superstructure and substructure. In the present work, the contact analysis have been performed which is highly nonlinear and required significant computational efforts following the points on one surface relative to lines or areas of another surface. The dynamic time history analysis has been performed on single storey masonry building, which is modeled and analyzed using ANSYS.
