Скачать или смотреть Strong Column – Weak Beam: A Key to Ductile Buildings in Earthquake Zones

This short animation explains one of the most critical concepts in earthquake-resistant structural design — the Strong Column - Weak Beam principle.

✅ Key Points:
What it means:

Beams should yield before columns during seismic activity.

Columns must stay intact to avoid total building collapse.

Why it’s important:

Enables energy dissipation through controlled beam damage.

Prevents brittle failure in columns that hold vertical loads.

Enhances overall ductility and safety of the structure.

Design strategy:

Ensure moment capacity of columns - beams at joints.

Avoid under-reinforced columns.

Follow IS 13920 code for ductile detailing in seismic zones.
