Effect of Base Isolation under Different Soil Conditions

[摘要] Severe seismic activity is a cause of grave concern for all kinds of structures. In order to safeguard buildings from earthquakes we use novel techniques based on performance-based seismic design. The base isolation method is one such technique utilized to reduce the effect of large-scale vibration produced during a seismic vibration. In this paper, we analyze two models: the first G+6 building and the second G+18 building using Lead Rubber Bearing (LRB). The analysis is done using ETABS software and here we use the non-linear time history method. Using the soil intrinsic effects like flexibility and stiffness, this research considers variation in displacement, drift, and repositioning of the soil in accordance with IS code 1893:2016. A greater spectral displacement was detected in medium soil in a fixed base structure. The time period for Lead Rubber Bearing building is greater than the conventional building. Base shear is minimized in (LRB) Lead rubber bearings as compared to a conventional building.
