Damage to CSU Parking Structure
Northridge Earthquake 1/17/94
Inadequate performance of floor diaphragms

Precast Concrete Buildings
• Half-scale model 3-story parking garage
tested on outdoor table at UC San Diego;
model weight ≈1,000 K
• Results give insight into complex
interaction between ‘jointed’ diaphragms
and primary lateral load resisting
elements
