Global interstory drift angle capacity C for regular SMF [21].

Building height	Performance level
	Immediate occupancy	Collapse prevention
	Interstory drift angle capacity C	Interstory drift angle capacity C
Low rise (3 stories or less)	0.02	0.1
Mid rise (4–12 stories)	0.02	0.1
High rise (>12 stories)	0.02	0.08
