Abstract:
In the present paper, the RC-framed fixed-base
buildings are compared with the RC-framed base-isolated
buildings using the geotextile as an isolator. As the cost of
the traditional isolators is much higher, emphasis is given
here to test the friction isolator by modelling RC-framed
buildings using SAP 2000. The values used for the friction
isolator were determined in the laboratory test using actuator which were found to be 42,000 kN/m, and average
coefficient of friction was 0.67. The present study is aimed
at ascertaining the applicability of the unified performancebased design (UPBD) method in carrying out design for
performance level in displacement-based design of RCframed buildings and comparatively study the performances of the RC-framed buildings with fixed-base
building and base-isolated buildings using UPBD method.
The performance parameters have been evaluated by performing nonlinear time history analysis for RC-framed
buildings with fixed-base and base-isolated for mid-rise
buildings.
