MATERIALS AND FRACTURE INVESTIGATIONS IN THE FEMA/SAC PHASE 2 STEEL PROJECT

摘要

The 1994 Northridge, California earthquake caused significant widespread damage to a large number of welded steel moment resisting frame buildings. As a result of this damage, a large effort has been undertaken to understand the potential causes of the damage, and to develop improved practices that will mitigate the same type of damage in future events. Phase 2 of the FEMA/SAC Steel Project includes a series of investigations of the properties of rolled shape materials used in moment resisting frame structures. The results of these materials investigations will be summarized in this paper.
