39. Methods of Introducing Ductility into RC Structures – Design Methodology (IS 1893, IS 13920 and IS 4326)
Ductility in RC structures is critical for absorbing and dissipating seismic energy, preventing sudden failure during earthquakes. Various standards, such as IS 1893, IS 13920, and IS 4326, provide methodologies to ensure ductility through proper design and detailing. Key strategies include capacity design, avoidance of over-reinforced sections, and use of advanced materials and techniques.

What we have learnt
- Ductility allows structures to withstand large deformations without significant loss of strength.
- Proper detailing according to IS standards enhances ductility and ensures safety during seismic events.
- Advanced retrofitting and modern materials increase the ductility and overall performance of RC structures.
Key Concepts
- -- Ductility
- The ability of a structure to undergo large deformations beyond yield without significant loss of strength.
- -- Capacity Design
- A design approach ensuring that structures fail in a ductile manner, typically with beams yielding before columns.
- -- Plastic Hinge
- A location where a structural section yields and bends under loads, designed to dissipate energy during seismic events.
