In response to the expanding exposure of buildings to abnormal events, Karl Rubenacker uses a 30 story high-rise office building as a case study to present practical methods and verification procedures by which structural engineers can incorporate disproportionate collapse resistance into their buildings as part of an overall multi-hazard design process.

The objective of the Metropolitan Section Structures Group is to advance the science, the practice, and the profession of structural engineering. To achieve this objective, the Structures Group provides the local community of bridge and building engineers and construction professionals with a forum to discuss the current issues affecting the practice. Each year, the Structures Group organizes technical lectures and the Seminar Series to provide opportunities for continued education and inform the engineering community of the state-of-the-art in the profession.
