EARTHQUAKE BASE-ISOLATED BUILDINGS Vasant Matsagar and Radhey Shyam Jangid

Fundamental working principle of earthquake base-isolated structures is presented using analytical shear beam model and discrete 2D and 3D models. The behavior of base-isolated building and influence of the shape of isolator force-deformation loops on its response is studied. The effects of torsional coupling, due to isolator parameters such as the isolation stiffness and/or yield strength, on the seismic response of base-isolated buildings are computed along with the other sources of asymmetries. The dynamics of impact problem in base-isolated buildings is studied through closed-form solutions for shear beam model, wherein free-vibration and earthquake-induced forced-vibration analyses are carried out. The seismic response of multi-story base-isolated symmetric and single-story asymmetric buildings during impact with the adjacent structures under earthquakes is studied. Performance of various isolation devices used in practice categorized as elastomeric and sliding systems is...
