Abstract

This study describes the results of field investigations and analyses carried out on 61 corrugated metal pipes (CMP) which were shaken by the 1994 Northridge earthquake. These CMPs, which include 29 small diameter (below 107 cm) CMPs and 32 large diameter (above 107 cm) CMPs, are located within a 10 km2 area encompassing the Van Norman Complex in the Northern San Fernando Valley of Los Angeles, California. During the earthquake 28 of the small diameter CMPs performed well while the 32 large diameter CMPs underwent performances ranging from no damage to complete collapse. The large pipes were analyzed using a strain-based pseudo-static analysis method, which shows that the main cause of damage to the large diameter CMPs was the large ground strains. Results of this field investigation and analysis are useful for the seismic design and strengthening of flexible buried conduits.
