Seismic performance evaluation of exterior beam-column sub-assemblages designed according to different codal recommendations
In the present study, seismic performance of exterior beam-column sub-assemblages is evaluated by considering different stages of Eurocode (EC) and Indian Standard (IS) provisions for design of the reinforced concrete structures. The study has brought out the implications of the differences in the guidelines on seismic performance. It is found that the gravity load designed (GLD) structure is vulnerable to even medium intensity earthquake. Among the seismically designed specimens without ductile detailing, the one which was designed as per IS exhibits better performance compared to that designed according to the EC with 10% more energy dissipation under large drift ratio. Among the seismically designed and ductile detailed specimens, the one designed as per EC provisions for medium ductility could not perform as good as that designed as per ductile provisions from IS (25% less energy dissipation). Stiffness degradation of the specimens is also found to be a crucial parameter and varies considerably among the specimens. Therefore, earthquake design and ductile detailing provisions of different standards and their progressive improvements have considerable influence on seismic performance of reinforced concrete structures.
