Last year marked two milestones for forensic structural engineer Donald O. Dusenberry. He retired from Simpson Gumpertz & Heger Inc. after 45 years and he celebrated the completion of the draft of the nation’s first building standard on disproportionate collapse mitigation.
This summer, the Structural Engineering Institute of the American Society of Civil Engineers expects to release, for public comment, a draft of the first U.S. consensus standard addressing disproportionate collapse of structures.
