The storey drift limits shall conform to IS 1893. The deformation compatibility of members not designed to resist seismic lateral load shall also conform to IS 1893 (Part 1).

Figure description:
- Subject: Partial penetration groove weld in a column splice.
- Key Formula: , specifying minimum axial force at the splice location.
- Visual Components:
- Cross-section of two column sections joined.
- Dark shaded regions indicate the location of partial penetration groove welds on the exterior.
- Vertical arrows denote applied axial loads.
- Technical Context: Related to seismic design standards (IS 1893 for storey drift and deformation compatibility.
