• Providing seismic links and confining reinforcement

• Reducing column sizes

In seismic zones, IS 13920 recommends detailing of reinforcement to ensure:

• Brittle failure

• Ductile failure

• No failure

• Fatigue failure

What is the purpose of providing transverse reinforcement in beams as per IS 13920?

• Increase axial load capacity

• Improve fire resistance

• Enhance shear strength and ductility
