This animation explains the difference between seismic and non-seismic column design based on Indian Standards (IS Codes). In earthquake-prone areas, special reinforcement detailing is required to ensure ductility and energy dissipation, reducing structural failure risks.
Key Differences:
Seismic Design (IS 13920):
Uses 135° bent stirrups with a hook length of 10 times the bar diameter (φ) or ≥ 75 mm for better anchorage.
Provides higher confinement to concrete, improving ductility and earthquake resistance.
Non-Seismic Design (IS 456):
Uses 90° bent stirrups with a smaller hook length of 6 times the bar diameter (φ).
Suitable for low seismic zones, but lacks the additional confinement required for earthquake resistance.
Why is this important?
Ensuring proper detailing in seismic zones minimizes structural damage and enhances building safety.
Following IS 13920 guidelines is mandatory for earthquake-resistant structures.
