Thank you all for actively participating in the live technical discussion related to draft IS 1893 (Part 1) on 18-MAY-23. If you have missed out the session, then you may go through the recording at following link:

Recently, BIS has published draft standard of IS 1893 (Part 1) and IS 1893 (Part 2).

• Draft standard of IS 1893 (Part 1) contains general provisions on earthquake hazard applicable to all structures.
• Draft standard of IS 1893 (Part 2) contains provisions specific to earthquake resistant design of buildings.

?There are significant changes proposed in the draft standards, few of the same are mentioned below:

?

IS 1893 (Part 2)

• Criteria are added for masonry buildings and steel buildings
• Response reduction factors are modified and renamed as Elastic force reduction factors
• Provisions on torsion is updated
• Structural plan density of the structural walls is varied with earthquake zone
• For RCC buildings, stiffness modifiers have same values for strength and serviceability
• Limits on lateral storey drift in building is mentioned with respect to seismic zone
• Concept of torsional flexibility is added
• Provisions added for buildings on sloping ground
• Displacement calculations added for Architectural elements and utilities
• Admissible structural systems in RC buildings for different earthquake zone is added.
• Admissible structural systems in Steel buildings for different earthquake zone is added.
• For steel buildings, for seismic zone 4, SMRF and EBF are suggested. For zone 5 & 6, only EBF is allowed, etc.
