Abstract - Bracings, shear walls, dampers, base isolation etc
Zone IV: A high seismic hazard zone with Zone factor (Z) = 0.24. Zone V: A very high seismic hazard zone with Zone factor (Z) = 0.36.
are the earthquake resistant techniques adopted to the building to safeguard it from the hazourdous effects of earthquake. The main purpose of this project is to analyze the G+10 residential building with and without Rubber bearing. Two models of the building were created one with rubber bearing and other with fixed support subjected to Dead load, live load and Earthquake load in combination as per IS 875 (part 1&2) and IS 1893-part1. The building considered to be located in zone V. Both the models were analysed and are compared on the basis of storey displacement, storey shear, storey drift, and base shear and are illustrated in the form of chart. The results show that storey displacement, storey shear, storey drift, and base shear values were much less in case of model with rubber bearing when compared with model with fixed support.
In Base isolation techniques, superstructure is separated from foundation using flexible interfaces such as elastomeric bearings, lead rubber bearings, Sliding systems etc. which allows the buiding to move independently during earthquake thus reducing force transmitted from ground to the building during earthquake.

1. INTRODUCTION Earthquakes are the most destructive of natural hazards. Earthquake occurs due to sudden transient motion of the ground as a result of release of energy in a matter of few seconds. The impact of the event is most traumatic because it affects large area, occurs all of a sudden and unpredictable. Vibrations induced in the earth’s crust due to internal or external causes that virtually shake up a part of the crust and all the structures and living and non-living things existing on it they can cause large scale loss of life, property and disrupts essential services such as water supply, sewerage systems, communication, power and transport etc. Software used are AutoCAD Software and ETABS Software. ETABS software used in the project stands for Extended Three-Dimensional Analysis of Building Systems.
2.2 Building specifications
In this work following building details are considered No. of stories = 10 Height = 37 each bay @3m Site Plan dimensions- 100’X50’-8.4” Location = Bengaluru Concrete grade M25 Steel grade HYSD500
As per IS 1893-part1, India is divided into five zones based of sevearity in occurance of earthquake. Zone II: A low seismic hazard zone with Zone factor (Z) = 0.10. Zone III: A moderate seismic hazard zone with Zone factor (Z) = 0.16.
