The 1200 L Street Building

The 1200 "L" Street Building in Anchorage, a fourteen-story reinforced concrete apartment building, was severely damaged during the earthquake. One the main exterior piers (the white bearing walls without windows)shown in this slide, failed at the second floor, exposing the steel reinforced bars within the concrete. The reinforced concrete spandrels (green nonbearing panels under windows) failed mainly by "X" shear-cracking between the piers and horizontal cracking at the floor lines near the corner of the building.
