| Abstract | Due to the rising growth of urban population, the need to develop tall buildings is also increasing. At present tall buildings are being designed using code-based design (CBD) and performance based design (PBD) which ensure “collapse prevention” and “life-safety” for building occupants in design level earthquake (DBE) shaking. The potential damage of the building’s structural and non-structural components is not considered in CBD and PBD; which become a deciding factor in terms of re-occupancy of a structure after the earthquake. Therefore, Resilience Based Design is the next step in the evolution of tall building design. For this study, a 51-story tall building was taken, and we check how changes made to it after performance based designed (PBD) analysis impacts the Resilience Rating. To show this implication we compare it with a model of the same building before the PBD analysis recommendations were added to it, i.e. the code based designed (CBD) model. The resilience rating is calculated for both the models (after PBD and before PBD) are subjected to Design Based Earthquake (DBE) ground motion. To find the resilience rating we use the REDi™ rating system along with FEMA P58 methodology to compare the component damage, downtime and direct economic loss. Based on the results we see that both the CBD and PBD models fail to get higher than silver REDi™. However, the PBD model shows 2% less structural component damage when compared to CBD model. In conclusion we see that to get a satisfactory level of resiliency rating ie. REDi™ gold or above CBD and PBD is not sufficient and resilience-based design needs to be carried out. |
