A partially-collapsed parking structure on the campus at California State University in Northridge. The garage was of precast, post-tensioned construction and was built in 1991. The center columns were crushed resulting in caving-in of the floors and extreme bending of the external columns. No cars were in the structure at the time of the earthquake. A similar shear wall, post-tensioned parking structure built in 1991 was essentially undamaged. Image Credit: M. Celebi.
