Performance of RC Frame Base-Isolated Building with Geotextile as Isolator Using UPBD Method
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 S...

| description | 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 performance-based design (UPBD) method in carrying out design for performance level in displacement-based design of RC-framed 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. |
